Thunderstorms are typically approximately 15 miles in diameter and usually last an average of 30 minutes. Thunderstorms are termed severe when they produce hail of at least 3/4" in diameter and have winds in excess of 58 mph or produce tornadoes. Thunderstorms are very common in South Florida particularly during the summer when the weather is warm and humid and very unstable.

Severe Storm Watch

Favorable conditions exist for severe thunderstorms to occur. Severe storm watches are issued for a 4-6 hour period of time and can often include several counties. If a severe storm watch is issued, then it is important to stay informed so that you can take cover if a severe thunderstorm approaches.

Severe Storm Warning

When a warning is issued it means that a severe thunderstorm has been detected by radar. If a severe thunderstorm warning occurs then you should take immediate cover. Stay inside buildings with as many walls as possible between you and the outside. If you are outside when a thunderstorm occurs you should stay away from any metal objects or metal fences.

Prepare for a Thunderstorm

Always remove dead and rotting trees or branches that could fall during a storm causing human injuries or property damage.
