The National Hurricane Center said in its 4 p.m. CDT advisory that Hanna, which reached Texas shores as a hurricane Saturday, was about 35 miles west southwest of Monterrey, Mexico, and had maximum sustained winds of 35 mph.
“Additional weakening is expected as the center of Hanna moves farther inland,” the weather center said.
Rain totals of 6-12 inches in the area – with up to 16 inches in some locations – “will produce life-threatening flash flooding, rapid rises on small streams and isolated minor river flooding in South Texas,” the advisory said.
Liz Sommerville, a senior forecaster for the National Weather Service, said there is a chance of severe thunderstorms all day Sunday and strong winds, heavy rain and low-line, coastal flooding in the region, especially in the northern and southern parts of Port Aransas.
Flooding could reach 2 to 3 feet.
Hanna made landfall at 5 p.m. Saturday at Padre Island as a Category 1 hurricane with sustained winds of 90 mph. By 1 a.m. CDT Sunday, Hanna had weakened into a tropical storm. At 12:49 p.m., the city of Corpus Christi announced in a news release there were no fatalities from Hanna.
Bringing maximum sustained winds of 85 mph, Hurricane Douglas swirled about 85 miles east of Kahului, Hawaii, and about 140 miles east of Honolulu, the NHC said.
As part of its 11 a.m. HST update, the NHC indicated that Douglas was moving west-northwest at about 16 mph. That track is expected to continue over the next couple of days.
Referring to the storm as a “dangerous hurricane,” the NHC said its forecast indicates “Douglas will pass near, or over, the islands from Maui to Kauai today and tonight.”
Though a gradual weakening is expected, Douglas figures to maintain hurricane-force winds on its path through the islands, “bringing a triple threat of hazards, including, but not limited to, damaging winds, flooding rainfall and dangerously high surf,” the NHC said.
“It’s definitely going to be a triple threat,” said National Weather Service meteorologist Vanessa Almanza.
Douglas is projected to generate 5 to 10 inches of rain from Maui County westward to Kauai County. The NHC warned that up to 15 inches of rain could fall in elevated terrain.
