WCTV First Alert Severe Weather Guide

When we talk about severe weather, we are referring to hazardous conditions produced by thunderstorms. These hazardous conditions may include damaging winds, flash flooding, hail, and tornadoes.

A thunderstorm must meet at least one of the following qualifications to be considered severe:

• Wind gusts of at least 58 mph.
• Hail that is at least one inch in diameter (quarter sized).
• The capability of producing tornadoes.

The Storm Prediction Center issues a specific level of risk for the areas affected by severe weather. A level 1 is the lowest risk, and a level 5 is the greatest risk for severe weather. The diagram below outlines each level of risk and what can be expected within each level.

The National Weather Service can issue a variety of watches and warnings for specific weather events in specific areas. Here are the key differences between a WATCH and a WARNING:

• WATCH: All the ingredients needed for the weather event to happen, whether it be a tornado or severe thunderstorm, are available in the atmosphere.
• WARNING: The ingredients that were available in the atmosphere have come together, and the weather event is now occurring.

Here are a list of watches and warnings that are common in our area when severe weather strikes, as well as what they mean and the proper action that should be taken when they are issued. ]

• Tornado Watch: Be Prepared! Tornadoes are possible in and near the watch area. Be ready to act quickly if a warning is issued or you suspect a tornado is approaching.
• Tornado Warning: Take Action! A tornado has been sighted or indicated by weather radar. Move to an interior room or lowest floor of a sturdy building, and be sure to avoid windows. If in a vehicle or outdoors, move to the closest substantial shelter and protect yourself from flying debris.
• Severe Thunderstorm Warning: Take Action! Severe weather has been reported by spotters or indicated by radar. The warning area may be impacted by large hail or damaging winds. Take shelter in a substantial building.
