Heavy hail, harmful gusts of wind and tornadoes are expected to affect areas from the Ohio River Valley to the Persian Gulf Coast.
As the day progresses, the heat and humidity that accompanies May in the Deep South will help revitalize the atmosphere and areas of the Gulf Coast from East Texas to Florida Panhandle, which could see strong to strong storms until the arrival of the strong impulses that come with the advancing front.
Areas of Central Louisiana, Alabama, Georgia and Mississippi are more likely to see hail and wind damage in a straight line than tornadoes. But a tornado is still possible.
They could be just as harmful to a region that has already been hit by storms that have hit the country in recent days.
A tornado struck at least three cities in Mississippi on Sunday. On Monday, tornado and thunderstorm clocks stretched from the Mississippi to south-central North Carolina, including the Atlanta subway, where the tornado touched and caused extensive damage.
Just over 90 million people could experience hard weather on Tuesday. Nearly 28 million in the southeast could face the wrath of rain, lightning, hail, wind and possible tornadoes.
The weather in Georgia is turning deadly
The region is still in turmoil since the time it killed two people in Georgia.
A Houston County resident has died as a result of the weather that hit Monday, the Houston County Emergency Management Agency said in a news release. The 55-year-old woman was killed by a falling tree.
“When fire crews arrived, they found that a large pine tree had fallen in the living area of the home, causing significant damage to the roof and exterior walls. Tragically, the crews also discovered that Ms. Carla Harris, 55, was struck by a falling tree and sustained fatal injuries, “the Houston County Emergency Management Agency said in a news release.
A man more than 100 miles away in Douglasville, Georgia, was also killed after a tree fell on his car when a tornado struck Monday.
Douglas County Fire Department responded to reports of a tree car with a person inside around 10:36 a.m., according to a news release from county officials.
“When they arrived on the scene, they found the driver trapped inside the vehicle with power lines and wood from the vehicle,” Douglas County Communications Director Rick Martin said in a statement. “Firefighters had to remove the driver, whom we currently identify only as a man, until those closest to him are notified.”
Atlanta Mayor Keisha Lance Bothams tweeted photos of downed trees in her Southwest Atlanta neighborhood, while Drew Gegan, owner of a Fulton County Customs Warehouse, shared photos showing the building had suffered significant damage.
Rainy days can mean floods
Many states in the southeast have doubled their normal rainfall in the last month, so even 1 to 2 inches of extra rain can lead to flooding.
A flood will be possible in the south, thanks to the combination of heavy rainfall and all the rains that have fallen in recent days and weeks. Widespread rain of 1-3 inches is forecast in this region until Tuesday night.
“Heavy hail, harmful gusts of wind and several tornadoes are likely, along with rainfall levels above an inch per hour,” said the National Weather Service in Jackson, Mississippi.
Circles of thunderstorms and rain showers will run through the Ohio and Tennessee river valleys throughout the day on Tuesday. Further south, torn storms are likely to develop at noon from East Texas through Georgia.
This line of storms should weaken by Wednesday morning as it approaches the East Coast, but severe weather will remain possible in isolation.
