The Harris County Flood Control District is actively monitoring the potential for heavy rainfall starting late Tuesday afternoon into Wednesday. Residents should expect numerous thunderstorms with the potential for excessive rainfall rates. Currently, the main concern is for street flooding, but should excessive rainfall hit the same watersheds over and over again, some creeks and bayous could see significant rises.
A Flash Flood Watch will be in effect from Tuesday, starting at 7:00 p.m. until 7:00 a.m. on Wednesday. Widespread average rainfall amounts of 2-4 inches with isolated totals of 6-8 inches are possible.
The Flood Control District encourages residents to create an account and sign up for rainfall and water level alerts at fwsalerts.org. FWS Alerts allow residents to customize the sensors they receive alerts from and choose to receive them via text, email, or both.
HCFCD encourages residents to take the following precautions when heavy rainfall and potential flooding is expected:
Make sure storm drains and culverts are clear from debris. Clogged drains and culverts can prevent water from traveling to the bayous and tributaries, causing street flooding, and possible house flooding, depending on the amount of rain we receive.
In areas that normally experience flooding, move vehicles to driveways or in parking garages as the storm approaches.
Move emergency supplies and valuables to a high, dry place in your residence.
Never drive into high water. Turn Around, Don’t Drown! Less than two feet of water can float and wash away a vehicle. Be especially cautious at underpasses and at night when water across roadways can be difficult to see.
Refrain from discarding debris in areas bayous, streams and ditches. Debris should be put in trash bins and then brought inside into garages or backyards, away from drainage ditches and storm sewers.
