Tips for Being Severe Weather Prepared

Please share this post with friends, family, and coworkers. Information provided in this article is very important.

Below is a picture of the sunrise in Carroll County on the way into Kokomo this morning. Although we don't have a wide open ocean or mountains, there is nothing quite like an Indiana sunrise. 


Beautiful Indiana sunrises can sometimes help you forget how destructive mother nature can be. Everyone has been affected by a particular weather event, whether it was in early childhood or late in life. I remember the funnel cloud passing over my parents house from the 1998 tornado that struck Taylor High School. I also fondly remember watching one of two November 2013 tornadoes form just south of Russiaville, cross State Road 26 and strike houses just south of 500W, hit the neighborhood north and east of the American Legion Golf Course, and damage homes in the Cedar Crest neighborhood. Luckily, neither of these events caused deaths in Kokomo. Unfortunately, not all communities are lucky enough to go death free for severe weather events. One of the deadliest tornadoes in United States history, The Tri-State Tornado, occurred on March 18, 1925. This tornado traveled over 300 miles, claimed 695 lives, and injured over 2,000 individuals. See below the tornado track image below obtained from a NOAA review of the 1925 Tri-State Tornado.

This image depicts a hypothetical Tornado Watch that may have been issued by the Storm Prediction Center for the afternoon of March 18, 1925.  It covers an area 70 statute miles north and south of a line from 30 miles southwest of Farmington, Missouri to 15 miles south of Bloomington, Indiana.

The April 11th 1965 Palm Sunday Tornado Outbreak struck a little closer to home. A F4 tornado nearly destroyed Russiaville, Alto, Kokomo, and Greentown. The tornado was on the ground for 48 miles from Russiaville to Marion, killing 25 people through its path. I found a video of the damage on YouTube that you may find interesting.

You see, we aren't invincible. Severe weather HAS happened here, and COULD happen again in some form or another. It is our job to prepare for the worst and hope for the best. Events like these is why you should be Severe Weather Prepared.

Tips for Being Severe Weather Prepared

Severe weather happens everywhere in the United States and can strike at any time of the year. Yesterday, we discussed the differences between severe weather watches and warnings. The link for this post is: www.boileragandweather.blogspot.com. Scroll down and you can find the post titled "Understanding the Difference Between Severe Weather Watches and Warnings". Today's post is dedicated to helping you become Storm Ready to reduce your risk of being harmed or worse being killed. 

Before severe weather strikes, you should have a plan that is specific to you and your family. 
  • Have a supply kit with emergency supplies such as water, food, battery-powered radio, first aid kit, a whistle, flash light, disinfectant wipes, blanket, can opener, and sturdy shoes. You can store all of these supplies inside a small suitcase to help with survival needs during severe weather situations. You find a full list of supplies here:  https://www.wunderground.com/prepare/disaster_supply_kit.asp.

  • Establish a meeting place during times of severe weather. This should be a location that is the most interior location on the lowest floor within your home, an underground shelter, or basement. My parents home does not have a basement, but we found shelter in a closet underneath their stair case. If you are fortunate enough to have a close neighbor with a basement, make it a priority to have a backup plan to shelter with them.
  • Have a family communications plan established. Try to stay in contact with your immediate family to ensure they are safe. If all possible, use land phone lines to alleviate the amount of traffic on cellular networks. I remember during the November 2013 tornado, it was very difficult to make phone calls over cellular networks. Being a weather nerd, I call and contact family if I see storms that look to be severe in advance. 
  • Have a NOAA Weather Radio that alerts you for severe weather watches and warnings that are within your county. I would also recommend programming your NOAA Weather Radio to a two county radius around Howard County. This will help improve your warning time and keep you informed of incoming storms. REMEMBER: Not all locations within Howard County have alert sirens. Weather Radios can save lives! 
               
  • Pay attention to local storm team coverage on radio networks or news stations. Also, don't get upset when news stations interrupt your favorite television program... If they are interrupting your programs, there is definitely something serious going on. They are doing their jobs to make sure the public is informed of severe weather. The more warning time the public has, the greater chance for reducing potential injuries and deaths. Local radio stations, such as WWKI and Z92.5 have storm team coverage that you can tune into during severe weather events.

  • If you are not near a shelter location, DO NOT stop and shelter under road overpasses. Debris from a tornado can get lodged up underneath overpasses. It is recommended to find a low-lying ditch to seek shelter. DO NOT try to outrun a tornado. Leave the vehicle and shelter immediately. 
  • DO NOT storm chase, unless you are trained. Even then, I do not recommend storm chasing. 
As you can see, there are many things you can do to make yourself prepared for severe weather.

 If Tornado Warnings are issued for your county, SHELTER IMMEDIATELY!

Understanding the Difference Between Severe Weather Watches and Warnings

Often times, I hear of individuals who do not fully comprehend the difference between weather watches and warnings. Not understanding when to take cover and when to go about your business can make a difference between life and death. Because severe weather season is quickly approaching, I thought I would take some time to try to shine some light on this topic. This article will be followed up with another article on Thursday that discusses how you can be severe weather prepared!

FACT 1: The NOAA Storm Prediction Center issues all weather watches throughout the United States. You can find information from the Storm Prediction Center here: http://www.spc.noaa.gov/. 

FACT 2: The local National Weather Service office in Indianapolis, Indiana issues all severe warnings for Howard County and the majority of central Indiana. See this link for more information: http://www.weather.gov/ind/aboutus.

FACT 3: Purchasing a NOAA approved weather radio that notifies you when weather watches and warnings are issued for your area can help you stay informed of incoming severe weather. Even though you may find these very annoying, it seriously make a difference between life and death.

This section discusses the differences between weather Watches and Warnings

Severe Thunderstorms


Severe Thunderstorm Watch: A Severe Thunderstorm Watch means that the Storm Prediction Center in Norman, Oklahoma, feels that atmospheric conditions are favorable for severe thunderstorms. Note: This watch DOES NOT mean that severe thunderstorms have been spotted in your area. This DOES mean that you need to stay informed and ready to seek shelter if a Severe Thunderstorm Warning is issued.

Severe Thunderstorm Warning:  A Severe Thunderstorm Warning means that severe weather has been spotted by trained storm spotters or weather radar indicates severe storms in your area. Note: This means that there is high danger for personal injury and property damage if you choose to not find shelter. People are killed every year by severe thunderstorms because they choose to either not pay attention to issued weather warnings or don't have any way to be notified about severe weather. Severe Thunderstorm Warnings have the potential to be upgraded to a Tornado Warning if there is radar indicated rotation or a tornado spotted within the storm.

What are the characteristics of a severe thunderstorm?
  • Winds greater than 58 miles per hour.
  • Hail larger than 1 inch in diameter.

It is important to understand that severe storms can contain one or both of the previously mentioned characteristics. 
Tornadoes


Tornado Watch:  A tornado watch means that the given weather conditions are favorable for producing tornadoes within a particular area. Note: This DOES NOT mean that there has been a tornado sited in your area. It DOES mean that you should be ready to act quickly and find shelter if a Tornado Warning is issued within your county.

Tornado Warning: A Tornado Warning means that a tornado has either been sighted or detected by radar in your area. If a Tornado Warning is issued, TAKE COVER IMMEDIATELY. Find an underground basement, storm cellar, or the most interior room within a building.

Flash Floods


Flash Flood Watch: A Flash Flood Watch indicates that there is potential for very heavy rainfall in a short period of time that could cause flooding to quickly occur within particular locations. Locations that are more prone to quick flooding such low-lying areas near rivers and streams. Flash Floods last less than six hours.

Flash Flood Warning: A Flash Flood Warning is issued by local National Weather Service offices when flash flooding is occurring or will happen. Note: DO NOT drive through flooded streets. Misjudgment of the depth and speed of floods can lead to being stranded or even worse death.

Floods


Flood Watch: A Flood Watch is issued when conditions are favorable for causing abundant water to accumulate on land that is usually dry. Most flooding occurs along rivers and into flood plains. Floods can last for weeks, which is way longer than Flash Floods.

Flood Warning: Flood Warnings are issued in areas where flooding will happen or is occurring.

2016 Weather Update and Projections

Overview

This article serves as a weather update pertaining to observations through  March 10, 2016, and will look at the temperature and precipitation projections into late March. Data were obtained from the Midwestern Regional Climate Center (http://mrcc.isws.illinois.edu/) on 11 March 2016. Projections were obtained from the Climate Prediction Center (http://www.cpc.ncep.noaa.gov/). 

Before we get into these data we must go over a little terminology.

What is the difference between climate and weather?
Weather is the changes in variables, such as temperature and precipitation, over short period of time.
Climate is how the weather variables behave over long periods of time. 

What are Climate Normals and Departure from Normals?
Climate Normals are thirty year averages of weather variables such as temperature, precipitation, and snowfall. Climate Normals are often times just referred to as "Normals" and will be in this article. These Normals are produced once every ten years by the Natiaonal Centers for Environmental Information. The most recent Normals range from 1981 to 2010. Normals for January, February, and March are in the table below.


Departure from Normals refers to how much any given observed weather variable differs from the thirty year average. For example, say the average February temperature was 30F in Howard County. The normal temperature is 27.5F. Therefore, the departure from normal is +2.5F. Therefore, February was 2.5 degrees warmer than normal.

Observed Weather and Departure from Normals

January 2016

Through January 2016, temperatures were near normal to slightly above normal. The majority of Howard County was normal. The below-left image depicts the January Average Temperature Departure from Normal. On average, January temperatures were near 24F. Howard County precipitation (total liquid rain and snowfall) was drier than normal by between 1 to 1.5 inches below normal. 


February 2016

February temperatures were on average of 2 to 4 degrees F above normal for Howard County.  The image below-left represents the temperature departure from normals. The bottom-right is the precipitation departure from normals. Accompanied with that, was 0 to 0.5 inches drier than normal precipitation. Southeastern Indiana saw anywhere from 1 to 4 inches above normal precipitation for February. Through February, Howard County is just over an inch below normal for precipitation.


 

March 1 through 10

Because we have not observed all the weather in March, I have included the average daily temperature and total precipitation for the first 10 days of March. The below-left image is average temperature and below-right is accumulated precipitation. From this, we can see that the average temperature in March has been 42F, which is pretty warm for the beginning of March. Total accumulated precipitation is around 0.82 inches for the first 10 days of March, which is nearly 30% of the total normal precipitation for the month.



Weather Projections through Late March

The temperature and precipitation projections below were obtained from the National Weather Service Climate Prediction Center (http://www.cpc.ncep.noaa.gov/). These maps display the probability of warmer/cooler and wetter/drier conditions.

6 to 10 Day Outlook

For the short term outlook, there appears to be higher chances for above normal temperatures (bottom left). In western-central United States, we can see that they have high chances of being colder than normal. The probability of precipitation is slightly higher than normal in Indiana. Below normal rainfall is highly  probable in western United States. 


 8 to 14 Day Outlook

The cooler air looks to move toward Indiana within the next two weeks. Temperatures look to be near normal (bottom-left). Probability of precipitation looks to be around normal to slightly above normal (bottom-right).

Operation Pollinator Conservation


Let’s chat about the birds, bees, moths and wasps for a bit. These critters represent a small portion of the group known as pollinators, which provide essential services to our environment and support the production of more than 66% of the world’s crop species. Pollinator driven fruit and seed production provide nutrition for birds and mammals. In other words, we are very pollinator-dependent and without them there is a potential for decreased food variety and increased world food prices.
  

Over the past 80 years, bee populations have declined by an astonishing 50% for reasons such as habitat loss, disease, and enhanced pesticide usage. Pollinator conservation practices, such as pollinator meadows, could be implemented to help protect these declining bee populations. Pollinator meadows include native wildflower mixes and shrubs that aim to provide flowering plants for food, shelter, and water sources throughout the entire growing season. Unfortunately, pollinator meadows do not grow overnight. A lot of time and consideration pertaining to site selection, preparation, plant selection, planting techniques, and ongoing maintenance must be completed. These sites should be sheltered from pesticide applications, maintenance equipment friendly, supplied with adequate sunlight, limited in weed populations, provided with sufficient water as well as acceptable soil drainage for the selected plant mix requirements. Site preparation is the most important step in the whole process and should begin in the spring before the late fall planting. This step primarily includes the removal of perennial weeds and the reduction of surface debris. For high weed pressure situations, weeds may need mowed down and non-selective, short lasting herbicides may need sprayed.

The cheapest planting technique for establishing the meadow would be through broadcast seeding instead of transplanted plug plants. Plug plants will require consistent drip irrigation, which adds to the overall expense. Planting is recommended between October and December. Depending on the plot size, fertilizer spreaders up to full-sized seeders can be used for planting. Seed mix vendors and recommendations for soil type, moisture content, and affordability can be found through The Xerces Society for Invertebrate Conservation. Ongoing maintenance practices, such as mowing, string trimming, hand weeding, and spot-spraying with non-selective herbicides, should be applied. Limited irrigation will also reduce weed competition within your newly established pollinator meadow.
