The low pressure system will be moving along the Gulf Coast throughout the day. Some of the heaviest storms will likely be over the open Gulf waters, so the risk of severe weather shouldn't be over land, but more for the coastal waters today.
Heavy rainfall will be possible across areas of Texas and Louisiana through Sunday night. 1-3 inches can't be ruled out along the border of Texas and Louisiana. Keep checking with WeatherNation for more updates on this coastal low.
