Weekly Outlook

A Flood Watch remains in effect for the Coastal Plains. Heavy rain and lightning are expected with addition isolated pockets of up to 4 inches of rain possible. This rain may fall quickly in torrential downpours. Life threatening flooding is possible somewhere within the Flood Watch area. Stay weather aware and remember: turn around, don't drown.

Flash flooding can escalate quickly, turning heavy rain into sudden hazards whether you are on the road or at a campground. Stay prepared by enabling phone alerts, moving to higher ground immediately when a warning is issued, and never entering floodwaters in a vehicle or on foot.

Heavy rain remains possible over the Coastal Plains where a flood watch is in effect. Elsewhere, occasional showers are possible, but flooding is not anticipated. #txwx
