In brief: Due to wet soils and the potential for slow moving storms, we are instituting a Stage 1 flood alert for the Houston region through Saturday evening. Please be weather aware and mindful of the potential for high water on roads.
Good morning! We hope everyone’s weekend is off to a good start. Looking at the radar at about 8:30 am CT, things are largely quiet with the exception of a few showers over Galveston Island. However with a moisture-laden atmosphere, we expect to see the development of widespread showers and thunderstorms later this morning and lasting through the afternoon hours.
To be clear, rivers, creeks, and bayous within the Houston metro area are all within their banks. However for much of the region, particularly central Houston, our grounds are saturated such that any additional rainfall today will quickly run into streets. Therefore we are likely to see street flooding develop more quickly than normal.
In terms of rainfall, for most of Houston, things will be just fine later today. However atmospheric conditions are supportive of heavy rainfall, and today we expect some storm motions to be slow. Therefore whereas most of the region may see a few tenths of an inch of rainfall, parts of the area may see 3 or more inches. The best chances for heavy rainfall today appear to be in Harris County, but the suburbs are also at risk.
Given all of this, we think there is a decent chance of some street flooding (i.e. low-lying roads, some feeder roads, etc.) today where rains are heaviest. Please be weather aware this afternoon and take more time during rain storms. Conditions should dry out overnight, but some additional storms are possible on Sunday, albeit not to the extent we think the Houston region will experience today.
