Tropical Depression Eta expected to strengthen again into tropical storm

Nov. 6 (UPI) — Tropical Depression Eta is moving toward Cuba and the southeastern United States and is expected to grow into a tropical storm again on Friday.

The storm was a Category 4 hurricane when it arrived in Nicaragua on Wednesday, but weakened as it moved farther over land. Eta was producing heavy rain and life-threatening flooding in Honduras, Nicaragua and Belize.

In its noon CST update Friday, the National Hurricane Center said Eta was located about 95 miles east-northeast of Belize City, Belize, and 375 miles west-southwest of Grand Cayman. It had maximum sustained winds of 35 mph and was moving north-northeast at 6 mph.

Eta would again become a tropical storm once it reaches maximum sustained winds of 39 mph.

The storm is expected to strengthen into a tropical storm on Friday as it travels nearer to Cuba and the southeastern United States, where it could make landfall in Florida late this weekend or early next week.

The center of Eta will move over the western Caribbean through Friday, approach the Cayman Islands Saturday and arrive over Cuba Sunday.

Eta could reach hurricane force again on its way toward Cuba. AccuWeather meteorologists expect it to approach southern Florida as a tropical storm. Eta’s track shows it veering to the west when it reaches Florida and the storm could end up in the Gulf of Mexico, the NHC said.

“It appears that Eta will not just wither away over Central America this week as some part of the diminishing storm’s circulation is likely to survive and re-enter the western Caribbean, where the process of reorganizing and restrengthening is bound to occur,” AccuWeather senior meteorologist Mike Doll said.

Florida has largely dodged impacts so far in a record-setting Atlantic hurricane season, which has spawned 28 named systems.

No landfalls have occurred in the state yet this season, but forecasters say the region is not out of the woods. Eta may pose a significant threat to lives and property, and at the very least, an interruption in daily activities and travel late this weekend and early next week.

The water over the northwestern Caribbean is some of the warmest of the entire Atlantic basin and plenty warm enough to nurture a tropical system. Eta is forecast to spend about 36 hours over the warm waters of the northwestern Caribbean, which is enough to allow for strengthening.

Conditions are forecast to deteriorate over western Cuba, especially along the southern coast during Saturday afternoon and evening. Rounds of heavy rain, strong winds and surf are anticipated. The risk of flash flooding will increase, as will the potential for mudslides in the mountainous terrain.

The storm may have another opportunity to strengthen once it emerges over the Florida Straits to the north of Cuba during the day Sunday. At this time, forecasters expect Eta to approach the Florida Keys and South Florida on Sunday night.

Impacts in South Florida and the Florida Keys late this weekend to early next week will depend on the storm’s exact track and speed after its encounter with Cuba. The magnitude of wind, rain and storm surge anticipated in the Sunshine State could change over time as details on Eta’s erratic path and strength become more clear.

Provided that Eta strikes Cuba as a hurricane and maintains some strength while crossing Cuba on Saturday night, a potential exists for hurricane-force wind gusts of 74 mph or greater in part of the Florida Keys and the southern part of the Florida Peninsula on Sunday.

Forecasters said the most likely scenario is for Eta to emerge into the Gulf of Mexico after striking southern Florida, but there is the potential that the storm will linger near Cuba and Florida instead, or it could possibly even move north over the Bahamas.

Eta has made history and matched the strength of the strongest storm of the tumultuous 2020 hurricane season — Hurricane Laura — when its winds peaked at 150 mph earlier this week.

Eta joined the ranks of eight other tropical systems in the Atlantic this season and underwent rapid strengthening, which is defined by a tropical system that experiences an increase its maximum sustained winds by 35 mph within 24 hours.
