Saturday, July 25, 2020, 7:18 a.m. – After a seasonal lull, the Atlantic Basin hurricane season has resumed with tropical storms Gonzalo and Hanna.

The temporary hiatus of hurricane season in the Atlantic is over, with tropical storms Gonzalo and Hanna both spinning in the ocean.

The two appear poised to make an impact on the land this weekend, Gonzalo on track to affect parts of the Windward Islands, while Hanna strengthens to potentially reach the hurricane statues when it hits Texas.

TROPICAL STORM HANNA

In the Gulf of Mexico, Tropical Storm Hanna intensified overnight and is currently located about 180 km east-southeast of Corpus Christi, Texas, and is approaching land at near 15 km / h. A gradual west-southwest turn is expected by Saturday evening and is expected to continue through Sunday.

The storm’s maximum wind gusts are 110 km / h and the storm is expected to reach Category 1 hurricane status on Saturday before making landfall. Central Hanna is expected to make landfall along the Texas coast in the hurricane alert zone on Saturday afternoon or evening. A rapid weakening is expected after its displacement inland.

Hurricane and storm surge warnings are in effect for the central and west coast of Texas.

Hanna is expected to bring 150-300mm of precipitation to parts of southern Texas and to Coahuila, Nuevo Leon and northern Tamaulipas in Mexico, with around 450mm possible in isolated extreme cases.

“These rains can result in life-threatening flash floods, rapid rises on small streams and isolated minor to moderate river flooding in South Texas,” the NHC says.

Other threats include a dangerous storm surge, high winds and the possibility of a few tornadoes.

TROPICAL STORM GONZALO

Gonzalo, meanwhile, was located 285 km east of Trinidad, while maximum sustained winds were near 65 km / h, down from Friday.

Tropical storm warnings are in effect for Saint Vincent and the Grenadines, Tobago and Grenada, with little change in power expected before Gonzalo reaches the southern Windward Islands on Saturday. Weakening is expected after the storm moves over the southeastern Caribbean Sea and is expected to dissipate Sunday evening or Monday.

Gonzalo is heading west at nearly 30 km / h, with a slight west-northwest turn expected for the next two days. Gonzalo will cross the southern Windward Islands on Saturday afternoon or evening, then swing over the southeastern Caribbean Sea on Sunday.

Strong winds and storm surges aside, Gonzalo is expected to bring 25 to 75mm of rain, and up to 125mm, to parts of the southern Windward Islands, with potentially fatal flash floods. It is also expected to bring 25 to 50mm of rain in northeastern Venezuela.

According to Phillip Klotzbach, a meteorologist at Colorado State University, Gonzalo is the 7th oldest storm on record in the Atlantic Basin. The previous record belonged to Gert, who formed on July 24, 2005.

FALL MAY BE MORE EXTREME THAN NORMAL

The hurricane season in the Atlantic in the fall could be more extreme than usual, German reinsurer Munich Re said on Thursday.

The forecast La Nina weather conditions may intensify tropical cyclones, the agency said in a natural disasters report.

In the first six months of 2020, natural disasters resulted in losses of $ 68 billion, lower than the average for the past 30 years, according to Munich Re.
