From the NWS:
Harvey has weakened to a tropical storm this afternoon, as it meanders across central Texas. It will not move much Sunday through the middle of next week, which will keep us under the threat of heavy rains, floods, and isolated tornadoes in the outer rain bands.
Rain totals tonight through Friday will be: Southeast Texas 10-16 inches, East Texas 6-10 inches, Southwest Louisiana 5-12 inches, South Central Louisiana 4-9 inches, and Central Louisiana 3-7 inches. Due to the rains, expect to see river flooding as well.
The storm surge threat is decreasing. During high tides this evening and again Sunday morning, there could be one to two feet of water above ground level in low-lying areas of coastal southeast Texas and southwest and south central Louisiana.
The tornado threat is low, but we have had reports of tornadoes today, so be ready to take action if a tornado warning is issued. The low tornado threat will continue tonight into Sunday.
