In previous years, the annual Storm Spotting classes sponsored by the La Crosse NWS were well attended. Dozens of Richland County agencies and and residents from all walks of life, as well as those from surrounding counties, signed up for the course which was taught by Todd Shea of the La Crosse NWS station. Those who completed the two-hour class were given cards which identify them as certified Skywarn weather spotters. They will now be able to report weather occurrences they observe either using an online system, or by phone.

As for the Pine Valley Repeater ARES/RACES Storm Spotters, they report directly to the EOC via their HT’s or mobile radios. Some of the spotters were taking the class for the first time. One resident who lives north of Richland Center, said that he came because of an interest in the weather. Another said, “We live out in the western part of the county, at one of the highest points. Most hazardous weather comes into the county from the west so reports from my home would be of great interest to those hearing them. Not only that, but I have always been interested in clouds.”

Shae used a PowerPoint presentation to teach the features of clouds, and what those features mean about imminent weather. Video clips of tornadoes and severe thunderstorms were used to demonstrate the weather happenings observers can watch for. Shae also stressed the importance of reporting hail, wind damage and the appearance of cloud formations, which can be an alert to a coming tornado. The difference between funnel clouds which do not touch the ground and tornadoes was one lesson he emphasized. “Accurate identification of funnel clouds is a key to accurate reporting,” he said.

Some in attendance have been to the class before, and said there were new things explained from past years. It is important to note the updates.

The Pine Valley Repeater ARES/RACES Storm Spotters have worked with Emergency Management because they know the importance of the reports they make to a weather emergency when phone lines are down.

One point is always stressed: REPORT WHAT YOU SEE — ACCURATELY!

When going Mobile

When you go mobile and being on the road, even on a sunny day with no storms, driving a vehicle on a public roadway can be dangerous. When you add STORMS – with heavy rain, gusty winds, hail, blowing dust, etc. – the danger increases dramatically. To stay safe as a mobile spotter, keep these things in mind:

• If you can, try to spot with a partner – This allows the driver to focus on the road while the passenger watches the sky. This also provides an extra set of eyes to keep an eye on rapidly changing situations.
• Watch for water on the road – Hydroplaning is a serious threat for drivers, and it doesn’t take much rain to cause roads to become slick and hazardous.
• Obey traffic laws – Speeding, parking too close to the edge of the road and making sudden turns and stops on unfamiliar roads all spell trouble.
• Watch out for the “other guy” – Severe storms often draw a crowd of “gawkers”, from casual observers to organized groups of storm spotters. Be extra careful when stopping to view a storm, making sure to pull completely off roadways and keeping an eye out for traffic, even in places where you would never expect to see traffic.
• Make sure your vehicle is ready for action – A well-maintained vehicle with a full tank of gas is crucial for a mobile spotter’s safety and success.

Lightning

All thunderstorms produce lightning, and people are killed and injured each year by lightning. Storm spotters may put themselves as risk from lightning by being in the open, being on a hill or high spot (for better visibility, parking or standing next to metal fences or underneath power lines, standing close to camera tripods or using radio equipment attached to an antenna).

Remember that lightning typically provides no warning – the first strike that you see may be the last. Follow these basic lightning safety guidelines:

• Avoid being the tallest object, and stay away from other tall objects (like trees, power pole/lines).
• Don’t stand close to fences or power poles/lines. Even though you may not be in an area of frequent lightning, lightning can travel a considerable distance along these pathways.
• As mentioned before, you should not wait for some type of warning (hair standing on end, sounds on AM or other radio equipment, etc.) before taking shelter from lightning – the first strike from a storm could be the one that gets you. Treat lightning with respect and stay in a protected area when lightning is in the area. Stay in your car!
• CPR training is an excellent idea for all mobile storm spotters. Remember that a person struck by lightning carries no residual charge and CPR could save a life.

The Storm

If a mobile storm spotter is well trained, experienced and knowledgeable about severe storm structure and behavior, they can usually avoid becoming a victim of the storm itself. However, the environment in and near a severe storm can change dramatically in a short period of time, and these changes can catch you by surprise. These basic tips can help you stay safe:

• Avoid the most intense areas of storms – This seems obvious, but each year spotters, for one reason or another, make decisions that place them in the core of a dangerous storm. Storm chasers — not  the same as storm spotters — call this “core punching” and it’s a very dangerous practice for a number of reasons. First, you may drive into very large hail, which can damage your vehicle and injure you. Second, you could drive right into the path of a tornado with very little time to react. And finally, the core of the storm is a dangerous place with low visibilities, heavy rain, and violent winds.
• Keep your head on a swivel — When observing a storm, it is easy to lose focus and become fixated on some feature you’re watching. You should maintain awareness of what’s going on all around you and always mindful of a surprise event. This points out the important of spotting with a partner, who can be an extra set of eyes and ears to help you stay safe.
• ALWAYS have an escape route in mind — Mobile spotters should always plan an emergency escape route that will take them out of harm’s way should the storm change direction or otherwise threaten them. Determining that escape routes require a great deal of knowledge about the storm’s movement and behavior. A detailed set of current maps of your spotting area is a critical part of a mobile spotter’s go-bag, but be mindful of the fact that roads sometimes change before maps do, and they may not reflect reality in every case.
• NEVER drive into areas where water covers the road — This is especially true when you cannot be certain how deep the water is. Many people die each year by driving into flooded areas and drowning in their vehicles. Find another safer route.
• Keep your engine running — Especially when operating close to a severe storm You do not want to find out about a vehicle problem as a violent storm bears down on you.
  
• Be extra cautious at night — Obviously, it is more dangerous to deal with something you cannot clearly see. Storms at night present special problems for spotters and you should be extremely cautious when observing storms after dark.

FINALLY — If you don’t have much experience in storm spotting, start by teaming up with someone who does! 

Observing Weather Radar

When interpreting weather radar, you might see something like this: dBZ. What does this mean? This is used for reflectivity in meteorology. dBZ is related to the number of drops of water per unit volume and the 6th power of their diameter. It can also be related to rainfall rate. You will especially see this in the charts on the Weather Underground radar and the legend found on the La Crosse NWS radar.

In the table below, a guideline on the interpretation of dBZ factors are given. Hope this helps:
