Rain throughout the day caused several accidents. However, investigators say it was not the rain that caused two fatal crashes.
The first happened around 7:00 a.m. Friday on I-59 south near the Savoy exit.
Michael Griffin, 27, from Louisiana, died in the wreck. Troopers say it appears he may have fallen asleep at the wheel.
Later in the day, around 11:30 a.m., troopers worked another fatal crash, this time on highway 11-80 in Toomsuba.
According to investigators, Olice Williams, 70, of Toomsuba, lost control of the vehicle and ran into the Toomsuba tire shop.
No one else was hurt. Troopers are reminding motorists to slow down.
"Because a lot of the wrecks we have now are because of hydroplaning, and it's because folks don't slow down," said Lt. Ralph Smith of the Mississippi Highway Patrol. "If it says 70mph, they don't have to do 70 in the rain. They can drop it down to 50, 55 miles an hour and they'll be a lot better off."
Motorists are being reminded not to use cruise control in the rain because it can make it easier for a vehicle to hydroplane.
