Drenching Downpours to Focus on Florida, Southeast Wednesday

Drenching rain will expand across the Southeast states through Wednesday, bringing the threat of flooding and travel delays. Strong thunderstorms are also a concern for Florida.

After a wet start to the week, the Deep South will start to dry out on Wednesday as the storm system moves east. However, heavy downpours will instead focus across Florida.

Drenching rain will also expand northeastward on Wednesday to part of the southern Appalachians and the southern Atlantic Seaboard.

Those traveling along the Interstate 10 and I-20 corridors from Florida to Georgia and South Carolina should anticipate delays due to the rain and allow for extra travel time to reach their destination.

The storm system has the potential to bring thunderstorms that could unload a general 1-2 inches of rain with locally higher amounts, which can not only spoil outdoor plans, but could also lead to flash and low-lying area flooding.

Not only will downpours create disruptions for travel and outdoor activities across the region, but so will some other risks with the thunderstorms.

AccuWeather.com meteorologists believe that some of the thunderstorms will be capable of producing hail and damaging wind gusts on Wednesday over the Florida Peninsula.

The strongest of these storms may even produce a small number of waterspouts and tornadoes.

A few brief showers may linger over the region on Thursday, but in large, Thursday looks to be a dry day for the Southeast.

Dry weather is also expected to carry over into the weekend and even extend up into the Tennessee and Ohio valleys, good news for those planning on attending Saturday's Kentucky Derby.

Anyone with outdoor plans earlier in the week may want to consider moving their plans to Thursday or Friday when the weather will be more favorable for outdoor activities.

A trailing cold front associated with the storm system will mark an end to the heat that has been building from the Florida Peninsula to Mexico's Yucatan Peninsula.

According to AccuWeather.com Senior Meteorologist Alex Sosnowski, "Showers and storms associated with the front will bring cooling to the region, followed by less humid air in its wake."

"The same front will bring needed rainfall to parts of Central America, Cuba and the Bahamas as it moves along and begins to stall," Sosnowski said.

April has been a particularly wet month across the Southeast due to several slow-moving storms that soaked the region over the past several weeks.

City
April Rainfall
Mobile, AL 13.67"
Lake Charles, LA 13.17"
Gulfport, MS 11.83"
Slidell, LA 10.35"
Birmingham, AL 9.89"
Pensacola, FL 9.96"

Table shows rainfall totals in inches from April 1, 2015 through April 26, 2015.

This has left the ground saturated with water, meaning that it does not take as much rain to cause flooding issues as it normally would.

Mobile, Alabama, has been one of the wettest cities in the entire country this month from the series of storms, recording over 13 inches of rain.

This is nearly three times higher than their normal rainfall for the month of 4.79 inches.

According to the National Weather Service, there are still dozens of river gauges across the Southeast that are in either minor flood stage or near flood stage.

Now that the heaviest rain has passed these areas, there will be some time for the rivers to recede a bit going through the rest of the week.
