Tropical Storm Predicted to Make Landfall on Saturday; Rainfall Estimates Increased
The National Hurricane Center (NHC) has begun advisories on Tropical Depression 8 in the central Gulf of Mexico. Tropical Storm Watches have been issued for the Texas coast from Port Mansfield to High Island including Matagorda and Galveston Bays.
Recent model guidance brings the system to the Texas coast with 48-60 hours over the Gulf waters. Some show the system over Gulf water for 72 hours as the system slows near the coast. NHC forecasts a 45mph tropical storm slamming the middle Texas coast on Saturday.
Houston should be on the dirty side of the storm.
If this does reach tropical-storm strength, it would be named Hannah. Ironically, another H storm hit Houston called Harvey in 2017. But Harvey happened a full month LATER in the season.
Next USAF reconnaissance flight will depart at 4:45 a.m. CDT tomorrow morning and will determine if a tropical depression or tropical storm has formed.
Jeff Lindner, Harris County meteorologist, says predicted rainfall rates have increased. Widespread rainfall amounts of 3-5 inches will be possible along and generally south of HWY 105 with higher isolated totals. North of HWY 105 rainfall amounts of 1-3 inches will be possible. There is likely to be swaths of higher rainfall amounts where training bands develop, but where this may occur is difficult to pinpoint at this time range.
Channel 13 tonight predicts that some areas west of Houston could record a three day total of 14-15 inches of rain because of the slow speed of the storm.
