As Tropical Storm Allison moves eastward, Oklahoma has been getting the worst of the storm.
In the early morning hours Wednesday, Allison was moving at a rate of up to 15 mph, the National Weather Service says.
Allison is expected to continue to move northeastward until Thursday morning, when it will head north of the state, which is already under a high wind advisory for the entire weekend.
Allison has brought widespread damage to Oklahoma and the Gulf Coast, including at least three tornadoes.
The storm has already brought heavy rain to parts of Oklahoma, including parts of Tulsa and Oklahoma City.
According to the National Hurricane Center, Allison is forecast to move over the Gulf of Mexico on Thursday morning.
Allison will become a Category 3 storm on Friday.
In Tulsa, officials warned residents to avoid the city.
Allison also could cause flooding and damage to roads and power lines.
“If you have to use the highway in Tulsa, stay off the highway,” Oklahoma State Highway Patrol Sgt. Gary Smith said Wednesday morning.
The agency has also asked anyone who was in or near an area affected by the storm to leave.
“Stay away from areas of concern,” the agency says on its website.
The Oklahoma City Police Department has also warned residents about the storm’s possible impact on the city, and advised them to stay away from homes and businesses.
As Allison moves westward, the storm is expected, with high winds and isolated storms moving into Oklahoma on Thursday, the NWS says.
The NWS said that some of Allison’s strongest winds will be on the East Coast, with gusts of up 50 mph possible, and that the storm could reach the Southeast.
The hurricane has already generated heavy rain in some parts of the Plains.
The National Weather Agency issued a severe thunderstorm watch for much of the Eastern Seaboard, which includes Oklahoma City, and the Atlantic Coast.
Allison was initially a Category 1 hurricane when it made landfall on May 6, but the National Oceanic and Atmospheric Administration (NOAA) later upgraded the storm from a Category 4 to a Category 5 hurricane, according to the NOS.
Allison’s wind speed is forecast for an average of about 15 mph (26 kph) as it moves northeastward, according the NNOAA.
The strong storm system is expected Wednesday to reach Oklahoma by Thursday morning as Allison heads south, and will be moving westward as it makes its way north, the Weather Service said.
