The National Weather Service Houston/Galveston office lists a Coastal Flood Advisory for local bays and beaches and says scattered showers with a few thunderstorms are likely across the region on Saturday, affecting the houston weather forecast into the night.
NWS’s Houston/Galveston page says scattered showers and storms are expected overnight with light easterly winds and low temperatures in the 60s and 70s, and it includes “Coastal Flood Advisory” under Current Hazards for the area.

Local coverage from ABC13 notes that Flood Advisories have been issued in the Houston area during recent rounds of heavy rain, and that advisories have accompanied road closures and reports of standing water in parts of Harris County. ABC13’s report is cited as background for how coastal and nearshore flooding has affected travel during similar advisories.
On the surface-observation map, multiple reporting sites around Houston showed mist or light rain and humid readings this morning, consistent with the NWS forecast that rain chances will be higher east of I-45 during the daytime period.

What residents should watch for
The NWS page advises that coastal locations should monitor tide-related flooding as minor coastal flooding can accompany onshore flow during periods of sustained easterly winds and higher tides. The office also provides local marine and beach forecasts for Galveston Bay and nearby zones.
Broadly, houston weather impacts from these systems include travel delays from surface flooding and localized street flooding where heavy downpours slow drainage. Local media coverage has previously linked Flood Advisories in the region to road closures and rescues when storms produce several inches of rain in a short time.
