This is a bit off topic for a flood blog, but it affects tens of thousands of readers. Late yesterday, after multiple heat records were broken across the region, the City of Houston announced water-use restrictions going into effect Sunday, August 27, 2023. Let me address the heat first, water restrictions second. Then I’ll discuss rain chances and the tropics.

CoH Water-Use Restrictions
According to a City of Houston press release, Houston has entered Stage Two of the City’s Drought Contingency Plan. Due to intense heat and a significant drop in annual rainfall. Effective August 27, 2023, mandatory water-use restrictions will go into effect. They apply to the entire City:
- Limit outdoor watering to twice a week between the hours of 7PM and 5AM
- Sundays and Thursdays for single-family residential customers with even-numbered addresses
- Saturdays and Wednesdays for single-family residential customers with odd-numbered addresses
- Tuesdays and Fridays for all other customers
- Any outdoor water use that results in city water leaving your property (i.e., draining onto adjacent property, or streets or gutters) is unlawful.
Violations of watering times will get you a written warning for the first violation. Any subsequent violations are subject to a fine up to $2,000 for each occurrence; see Section 54.001 of the Texas Local Government Code.
Easy Ways to Conserve Water
Here are some easy ways to conserve water:
- Check and repair water leaks, including dripping faucets and running toilets.
- Check sprinkler heads to make sure water is not spraying into the street or directly into a storm drain and/or gutters.
- Avoid washing sidewalks, patio furniture or cars. If you must wash your car, use a car wash. Most car washes use recycled water.
- Run dishwashers and clothes washers only when full.
- Take shorter showers.
- Install a rain barrel and use it for outdoor watering.
- Turn off the water when you are not using it (e.g., while brushing teeth or shaving).

The high-pressure ridge parked over us for the last two months is giving a little bit of ground. Yesterday, thunderstorms finally overcame subsidence in the super-heated afternoon air mass. The gage at the West Lake Houston Parkway bridge recorded 0.44 inches of rain. Despite several downed trees, people cheered because of our deep drought.
According to Jeff Lindner, Harris County Meteorologist, as high pressure moves west, weak disturbances may approach the area from the east and northeast.
Combined with high temperatures in the low- to mid-100’s, scattered thunderstorms will be possible.
Wildfire Risk Remains
Thunderstorms come with the threat for lightning-induced wildfires. One such fire started yesterday in the Humble area. Lightning strikes will be possible each day and strong gusty winds can quickly fan fires.
Additionally, wind direction and speeds can quickly change near and around thunderstorms creating very hazardous conditions for ground crews. Multiple fires caused by a single thunderstorm can quickly overwhelm local resources. So use extra caution. Burn bans remain in effect.
Western Caribbean Sea
An area of low pressure has crossed Central America into the western Caribbean Sea. It should move north toward Florida. As of this morning, the National Hurricane Center gave it a 70% chance of formation during the next 7 days.
However, it remains unclear where exactly any surface low will form and how it may interact with the surrounding landmasses. Additionally, there may be wind shear to contend with in the southeastern Gulf of Mexico. At this time, models predict varying intensity as the storm moves north.
Currently, this system does not pose a threat to Texas. But watch for winds that could enhance our local fire weather.
