Hurricane Sally Could Bring Historic Flash Flooding Along Mississippi, Alabama, Florida Coasts

This year’s hurricane season is on pace to be the most active of all time, so it’s no wonder that the tropics remain very busy.

The National Hurricane Center now sees four named storms and seven active systems in the Atlantic storm basin.

Tropical Storm Sally remains a hurricane headed for the Gulf Coast, though it was downgraded to a Category 1 storm at 2 a.m. EST. As of 11 a.m., Sally’s winds are up to 85 mph with 115 mph gusts.

The strength of the storm isn’t the main concern. Sally is only moving at 2 miles per hour. That slow movement, means it is going to drop an incredible amount of rain for an extended period of time.

Couple that with any significant wind speed, and you have a recipe for major damage. The National Hurricane Center warns Sally could bring "historic life-threatening flash flooding through Wednesday."
