This evening, the NHC upgraded TD No. 8 to Tropical Storm Hanna. The overall track has shifted further to the south, but we could continue to see some shifts in the final path over the next 24 hours. The current forecast shows the storms center making landfall south of Corpus Christi.
Even with the potential path shifting further south, rainfall continues to be the biggest threat for the Greater Houston Area. The forecasts are continuing to show widespread 1 to 4 inches of rain with areas possibly seeing isolated higher amounts up to 6 inches. Higher amounts are possible with this event; however, based on the current track, the heaviest rainfall should remain near Matagorda Bay and to the south.
Although we should be able to manage the forecast rainfall amounts, we could see some periods with intense rainfall that could create some rapid rises in some of our creeks and streams in addition to some street flooding but like SpaceCityWeather said in their latest update:
We will of course continue to track this depression, and if our forecast thinking changes we will update post haste. For now, however, you can expect a gray and wet weekend, but likely one without widespread street flooding, or worse.SpaceCityWeather 07/23 3:29 PM Update
Our eyes are mainly on TD No. 8, but everyone is continuing to watch what TS Gonzalo might do. The main discussion is that it is still way to early to know what and how Gonzalo might impact the Gulf, especially the Texas Coast.
From some of the discussions, Gonzalo has become a little less organized today when compared to yesterday. The NHC continues to show TS Gonzalo possibly becoming a minor Hurricane on Saturday, but ultimately weaken to a Tropical Storm or even a Tropical Wave/Depression as it moves south of the Dominican Republic.
We will continue to monitor the conditions and changes in the forecast, but we encourage everyone to stay informed by visiting your favorite local weather source (i.e. SpaceCityWeather), including the National Weather Service, the National Hurricane Center, and West Gulf River Forecast Center. If you have not ready down so, please remember to sign up for Emergency Updates from Fort Bend County and/or Harris County.
