LOCALLY: We’ve had a mostly quiet night with a muggy mostly cloudy overnight and temperatures holding in the mid-70s.

Today, we’ll watch for more outer bands to develop as tropical moisture once again will get pulled onshore from the overall swirl to the atmosphere as Hanna moves into Mexico. Some downpours could be on the strong side, dropping a quick half an inch or up to an inch within an hour or so.

Saturday, 3 p.m. – Hanna is a CAT 1 hurricane with winds sustained at 85 mph with wind gusts to 100 mph. Winds are expected to hold around 85 mph upon landfall within the next few hours somewhere near Port Mansfield.

Although Hanna will make landfall safely south of Houston, impacts will be felt far away from the center of the storm. Outer rain bands will continue to move through Southeast Texas throughout the remainder of the day into this evening.

When storms rotate through expect quick, heavy downpours and brief gusty winds. Some rain bands will continue through tonight and even some for Sunday as well.

For the Houston area, there is a Flash Flood Watch for counties south of Harris until 7 a.m. Sunday morning. Two to four inches of rain are expected mainly south of I-10. Locally, higher amounts could occur in isolated locations.

Jackson, Brazoria, Fort Bend, Matagorda, Wharton and Galveston counties could experience isolated pockets of 5-6′’ of rain.

A Coastal Flood Warning is in effect for coastal portions of Galveston and Harris Counties as one to two feet of surge is possible. This includes Galveston Bay.

Coastal impacts will be larger from Sargent southward to Port O’Connor. Three to five feet of surge is possible in coastal areas of Matagorda and Jackson County.

The National Hurricane Center has issued a Hurricane Warning for the coast from Port O’Connor to the Baffin Bay.

Tropical Storm Warnings continue from Matagorda Bay southward past Port Mansfield, likely where the eye of Hanna will pass.

Current watches and warnings

After landfall, Hanna will push inland continuing into northern Mexico. This slow movement will allow for a strong onshore push for Southeast Texas for multiple days.

This persistent southeast wind will allow for a strong influx of Gulf moisture. This will allow for daily downpours and indirect impacts from Hanna through Tuesday.
