Before last week’s torrential rain, Houston was part of an unprecedented nationwide drought that affected 61% of the mainland United States. Then, in a sudden week of heavy rain areas of Northwest Harris County including Cypress Creek, Little Cypress Creek, Willow Creek, and Spring Creek, in Harris, Waller, and Montgomery Counties received 11-15 inches of rainfall. In comparison, the average weekly rainfall for this time of year is about 1 inch and rainfall in the entire Southeast Texas area last week was between 8 to 10 inches.
A flood warning is now in effect until 10 p.m. on Tuesday for Harris County and 4 a.m. Tuesday for Montgomery and Brazoria Counties. A flood warning is also in effect for Liberty County until 4 p.m. Monday.
For this week, scattered and isolated thunderstorms are forecast with up to a 40% chance of additional rain. By Sunday, the threat of thunderstorms is expected to recede, with partly cloudy skies and only a 20% chance of rain.
Last week’s heavy rain and flooding throughout the Houston area is an important reminder to be vigilant of flood conditions in Houston. Following are a few tips to safely prepare for any additional heavy rain that may be coming our way. Additional tips, as well as ways to discover if your home is in a flood zone are available at the Family Flood Preparedness Center.
1. Remove any dead branches from trees in your yard. Dead branches can become loose and cause damage to your home during thunderstorms.
2. Remove any excess debris from gutters in anticipation of heavy rain. Overflowing water from gutters can collect and cause roof damage.
3. If you have a swimming pool, lower the water before heavy rain is expected. Chlorinated water can be harmful to grass.
4. Keep all important documents such as passports, insurance information, birth certificates, and other important documents in a waterproof container. Keep these documents with you at all times.
5. Have a flashlight, spare batteries, radio, and a first aid kit on hand for potential emergencies.
