The heaviest amounts of rain should be behind us, but we could see additional showers through Sunday as the highest chances for rain shift to our north. For most of the Brazos River Watershed, including Fort Bend County, the forecast shows a week or so of sunny to partly cloudy skies. Overall the NWS anticipates less than a 0.5 inch of rain for the Brazos River Watershed over the next 24 hours.

The good news is now that the heavy rain is behind us we have a much clearer picture of the impacts to the Brazos River. Based on the amount of rainfall received the Brazos should peak below Action Stage (Gage Elevation 20). No flooding along the Brazos River through Fort Bend County is anticipated.
