Severe Weather Risks

NOAA's Storm Prediction Center issues outlooks for severe weather every day. High risk outlooks are rare and indicate either a tornado outbreak or widespread damaging winds are expected.

Severe Thunderstorms – Types and Classifications

About 10 percent of thunderstorms are classified as severe—one that produces hail at least three-quarters of an inch in diameter, has winds of 58 miles per hour or higher, or produces a tornado.

Severe Thunderstorms – Associated Hazards

Hazardous weather conditions can be packed into very concentrated zones in and around thunderstorms. Hazards include high winds, straight-line winds, large hail, icing, lightning, tornadoes, heavy rain and poor visibility.

Severe Thunderstorms – Introduction

Thunderstorms affect relatively small areas when compared with hurricanes and winter storms. The typical thunderstorm is 15 miles in diameter and lasts an average of 30 minutes. Despite their small size, ALL thunderstorms are dangerous!

Severe Thunderstorms – Warning Alert Notifications

Severe thunderstorm notifications and convective outlooks (AC) are issued by the National Weather Service's (NWS) Storm Prediction Center (SPC) in Norman, Oklahoma and have different order of severity.

Severe Thunderstorms – Mitigation (Actions Before, During, After)

When it comes to severe thunderstorms, it's better to take caution and seek shelter in a substantial building or storm shelter, as tornadoes can form very quickly. There are certain recommended actions that can help through each stage of a Severe Thunderstorm emergency.

Severe Thunderstorms – Vulnerability Assessment

Severe Thunderstorm vulnerability depends on the incidence of and societal exposure to them for a particular location. The greatest potential for severe weather develops in geographical regions that are subject to warm, humid air at low levels, while dry, conditionally unstable air prevails aloft and are most likely to occur in the spring and summer and during the afternoon and evening.

Severe Thunderstorms – Aspects and Features

Thunderstorms have three stages in their life cycle: The developing stage, the mature stage, and the dissipating stage.
