New thunderstorm warning will alert smartphone users when ‘destructive’ weather is threatening

Level of hail severity

ORLANDO, Fla. – In Central Florida, strong to severe thunderstorms can happen at any time of the year. It could be tracked along a strong cold front, embedded in a feeder band of a tropical system, or even develop during the collision of our daily afternoon sea breezes.

Within these more hazardous storms comes the risk for tornadoes, large hail, lightning and even flash flooding.

Starting on Aug. 2 the National Weather Service will better convey the severity and potential impacts of thunderstorm winds and hail, by adding a “damage threat” tag to severe thunderstorm warnings, similar to Tornado and Flash Flood Warnings. Warnings with this tag will automatically activate a Wireless Emergency Alert (WEA) on smartphones within the warned area.

Warnings with this tag will automatically activate a Wireless Emergency Alert (WEA) on smartphones within the warned area.

What qualifies as a “Destructive” and “Considerable” Damage Threat?

The National Weather Service developed three categories of damage threat for Severe Thunderstorm Warnings. They state that the categories go in order of highest to lowest damage threat and are designed to promote immediate action, based on the specific threats.

  • Destructive damage: There is a threat of at least 2.75-inch diameter (baseball-sized) hail and/or 80 mph winds. This tag will activate an “WEA” to smartphones.
  • Considerable damage: There is a threat of at least 1.75-inch diameter (golf ball-sized) hail and/or 70 mph winds. This tag will NOT activate a WEA.
  • Baseline damage: There is a threat of 1.00-inch (quarter-sized) hail and/or 58 mph winds. This will NOT activate a WEA. With this category, damage is expected to be at the base level.

To be alerted with ALL types of significant weather in your area, you can download the free Pinpoint Weather App from the app store.

How often do these types of storms occur in Central Florida?

On average, only 10% of all severe thunderstorms reach the destructive category each year, nationwide. And that percentage shrinks considerably across Central Florida.

Across our viewing area, we tend to see just a handful of these potentially “destructive” storms annually. These types of severe thunderstorms could be found anytime of the year here in Florida.

The last memorable storm that reached the “destructive” damage criteria was in May 2020. During this event, hail ranging from quarters to bigger than baseballs fell in Orange and Seminole County. The most impressive report was 3-inch sized hail in Sanford.

For those wondering, although hail that big is exceptionally rare, it is possible. The record for the Sunshine State still stands at 4.5 inches. This grapefruit-size hail has been observed on three occasions in Florida; in Polk County in March of 1996, Bradford County in March of 2003 and in Marion County on May 13, 2007.
