Overview
- A National Weather Service Flood Watch covers much of the Greater Houston area through early Sunday morning.
- The first line of storms is expected early Saturday, reaching Houston around 6 a.m. and clearing the city by mid-morning.
- A faster-moving second round is forecast late Saturday, arriving between 9 and 11 p.m. and racing to the coast around 1 a.m., with additional showers possible into early Sunday.
- Forecasters cite a level 2 flash-flood risk for Saturday into Sunday, with rapid street flooding possible where downpours persist.
- Severe threats include damaging winds and hail with a low, nonzero tornado risk, and officials advise keeping phones alert-enabled overnight as confidence is highest for the early event and lower for later rounds.
