Heavy afternoon showers had parts of Harris County on alert Monday, July 13, after the National Weather Service issued a Flood Advisory warning of quick-hitting street and small‑stream flooding that could snarl travel into the early afternoon.
According to National Weather Service Houston/Galveston, the advisory covered portions of Harris County and highlighted the risk of urban and small‑stream flooding. The product called out low‑lying and poor‑drainage areas as the most vulnerable and was scheduled to expire around 2:15 p.m. CDT. Forecasters also repeated the familiar warning to drivers: "Turn around, don't drown" when water covers the road.
Where flooding is most likely
Low‑lying neighborhoods and spots with notoriously poor drainage are expected to feel the brunt of the downpours. The county’s live monitoring tools track where water is rising in real time so residents can decide whether to head out or stay put. Through the Harris County Flood Warning System, people can check inundation maps and water‑level gages to see if nearby channels are creeping toward bankfull conditions.
Traffic and safety
Local transportation and law‑enforcement accounts quickly boosted the alert, and TxDOT‑HOU District retweeted the advisory to warn motorists about high water and slick roads while county precincts echoed the same concerns. Drivers are urged to slow down, steer clear of standing water and choose alternate routes instead of trying to push through flooded streets, since even a few inches can be enough to stall a vehicle.
For continuing updates, residents are advised to monitor the National Weather Service Houston/Galveston feed, check the Harris County Flood Warning System before traveling and keep an eye on local agencies' traffic posts. Officials stress that conditions can shift quickly and that any flooded roadway should be treated as impassable.
