NWS Houston/Galveston Update: Heavy Rain and Strong Storms Possible Later Today and Tonight

Fort Bend County Levee Improvement District 14 is actively monitoring the potential for heavy rainfall to move through the region Tuesday evening through Wednesday morning. Below is an update from the NWS Houston/Galveston Office.

Isolated to scattered showers and thunderstorms will continue through the afternoon, but then a line of strong thunderstorms will develop this evening and slowly move through the area later this evening. There is a Flash Flood Watch in effect from 7pm this evening through 7am Wednesday morning.

Overview

There will be isolated to scattered showers and thunderstorms through the afternoon today mainly south of I-10 that may produce isolated spots of 1 to 2 inches. However, the main concern will be from a line of storm thunderstorms that will develop over the northwestern portion of the region this evening and slowly move eastward through tomorrow morning. Widespread rainfall through Wednesday morning will average between 2 and 4 inches with isolated high-end amounts between 6 and 8 inches possible. The WPC has placed much of SE TX in a Slight Risk for excessive rainfall later today and tonight, and we have issued a Flash Flood Watch from 7pm this evening through 7am Wednesday morning. In addition to the heavy rain threat, the SPC has placed portions of the area in a Slight Risk for severe thunderstorms this evening and tonight with hail and strong winds possible. Confidence is high that rain will develop, but confidence in timing and location remains moderate to low since much of the activity will be driven by small scale features.

Urban Flash Flood Messaging

Heavy rainfall is forecast for portions of Southeast Texas, including highly urbanized areas like the Houston metropolitan area. Based on forecast conditions, NWS Houston will be utilizing the following urban flash flood messaging for this event:

Generally: Street Flooding (Anticipating Moderate Rainfall Rates; 1-2″/hour)

  • Drive with caution. Cars may flood in low-lying areas. Ponding on roadways may increase risk of hydroplaning.
  • Pay attention to the weather. Monitor the NWS, your local media, HCFCD and other official weather information sources.
  • Rain may move repeatedly across the same area, causing a rapid rise on creeks and bayous. However, creeks and bayous are not likely to exceed their banks.

Isolated: “Turn Around, Don’t Drown” Flash Flooding (Anticipating High Rainfall Rates; 2-4″/hour)

  • Turn Around, Don’t Drown. Isolated underpasses or low-water crossings may be life-threatening.
  • Monitor the NWS, your local media, HCFCD and other official weather information sources.

The District encourages everyone to follow good flood safety standards and stay informed through trusted sources such as the National Weather Service, West Gulf River Forecast Center, and the Fort Bend County Office of Homeland Security & Emergency Management.

Cristobal Update – June 4

NWS Tropical Depression Cristobal Briefing – Thursday, June 4, 2020 (PDF)

We are continuing to monitor the development of now Tropical Depression Cristobal. Currently, Cristobal continues to be inland over the Mexico/Guatemala border moving in the easterly direction. The National Hurricane Center 10:00 AM forecast shows TD Cristobal starting to move in a more northerly direction later today. As it approaches the open waters of the Gulf, the forecast shows TD Cristobal regaining Tropical Storm strength by Saturday. There continues to be some uncertainty in the overall path and impacts of Cristobal, but over the past 24 hours, the National Hurricane Center has focused their forecasts showing Cristobal reaching the Louisiana Coastline Sunday night into Monday Morning. Although we cannot specifically rule out impacts to Southeast Texas, the current path could mean minimal impacts to Fort Bend County and the Brazos River Watershed. The most severe weather, including heavy rain, would be on the “wet” or east side of the storm’s center.

The NWS Quantitative Precipitation Forecast includes both rainfall associated with Cristobal as well as rainfall not directly associated with the storm. Based on the forecast, the most severe rainfall is located over portions of the Gulf Coast, east of Texas. Based on the 7-Day QPF, the lower Brazos River could see less than ½ inch over the next 7 days. These rainfall amounts could change based on the actual development and path of Cristobal.

Based on the amount of rainfall received on Wednesday, we did see the Brazos River in Richmond flatten out; however, as of this morning the Brazos River from Hempstead to Rosharon continues to fall. By the weekend, levels should be at or slightly below our historical average for this time of the year.

We will continue to monitor the development of this system and provide updates. We encourage everyone to continue to monitor the forecasts published by the National Hurricane Center and stay informed through the Houston/Galveston NWS Office, the West Gulf River Forecast Center, and the Fort Bend County Office of Homeland Security and Emergency Management.

Weekly Brazos River Outlook

The Brazos River in Richmond is currently at Gage Elevation 21.24 and falling. The WGRFC predicts that the Brazos River through Richmond will fall out of Action Stage later today. Based on the 7-day extended forecast, no flooding along the Brazos River through Fort Bend County is anticipated.

This Week

The current forecast includes a mixture of sunny to partly cloudy skies with a chance for scatter showers and thunderstorms throughout the week. Our high temperatures should be in the upper 80s to low 90s with our low temperatures in the low the mid-70s. The NWS 7-Day Quantitative Precipitation Forecast (QPF) shows the majority of the Brazos River Watershed receiving less than ½ inch with some areas possibly receiving closer to ¾ inch.

All eyes are focused on possible tropical development in the western portion of the Gulf of Mexico. Remnants of Tropical Storm Amanda (East Pacific System) are anticipated to move across Guatemala and the Yucatan Peninsula over the next couple of days. As this system moves into the Gulf of Mexico, the National Hurricane Center gives it an 80% chance for tropical cyclone formation. If it forms, it would be named Cristobal. Although confidence has increased in its development, the overall strength and track is still unknown. Some modeling suggests this system could become a Tropical Storm to a moderate hurricane by the beginning of next week moving in a north or northeastern direction; however, until it moves into the Gulf and a center forms, the confidence remains low. LJA will continue to monitor the development of this system and provide updates as we approach the weekend. We encourage everyone to continue to monitor the forecasts published by the National Hurricane Center and stay informed through the Fort Bend County Office of Homeland Security and Emergency Management.
