The National Hurricane Centre said Isaias was strengthening slightly with sustained winds just under a Category 1 hurricane.

Bands of heavy rain from Isaias have lashed Florida's east coast, with the tropical storm strengthening slightly in the evening on its way up the Eastern seaboard.

Officials dealing with surging cases of the coronavirus in Florida kept a close watch on the storm that was weakened from a hurricane to a tropical storm on Saturday afternoon, but still brought heavy rain and flooding to Florida's Atlantic coast.

The National Hurricane Centre advised at 9 pm GMT on Sunday that the storm was about 105 kilometres off the east coast of Central Florida, and about 660 kilometres south of Myrtle Beach, South Carolina.

It was strengthening slightly with sustained winds just under a Category 1 hurricane, taking a north-northwest path, according to the centre.

“Don't be fooled by the downgrade,” Florida Governor Ron DeSantis warned at a news conference after the storm spent hours roughing up the Bahamas.

Downgrade to tropical storm

Upper-level winds took much of the strength out of Isaias, said Stacy Stewart, senior hurricane specialist at the hurricane centre in Miami.

“We were expecting a hurricane to develop and it didn't,” Stewart said on Sunday.

“It's a tale of two storms. If you live on the west side of the storm, you didn't get much. If you live east of the storm, there's a lot of nasty weather there.”

Authorities closed beaches, parks and virus testing sites, lashing signs to palm trees so they wouldn't blow away. DeSantis said the state is anticipating power outages and asked residents to have a week’s supply of water, food and medicine on hand. 

Officials wrestled with how to prepare shelters where people can seek refuge from the storm if necessary, while also safely social distancing to prevent the spread of the virus.

In Palm Beach County, about 150 people were in shelters, said emergency management spokeswoman Lisa De La Rionda. The county has a voluntary evacuation order for those living in mobile or manufactured homes, or those who feel their home can't withstand winds.

“We don't anticipate many more evacuations,” she said, adding that the evacuees are physically distant from each other and are wearing masks, due to the virus.

In Indian River County, north of West Palm Beach, Florida, emergency shelters were clearing out Sunday after Isaias was downgraded to a tropical storm.

Officials told TCPalm newspapers that 38 people registered at three schools used as shelters. Those areas now must be cleaned to ensure no traces of the coronavirus remain as teachers and staff report on Monday to prepare for the upcoming school year.

No one checked in with Covid-19 symptoms. Temperature checks were done at the door, officials said, and isolation rooms were designated in case anyone came in with symptoms.

Sliding towards Georgia and southern South Carolina

The storm's maximum sustained winds declined steadily throughout Saturday, and were at 100 kph at 6 pm GMT on Sunday, before crawling back up to 113 kph a few hours later, the hurricane centre said.

“The centre of Isaias will move offshore of the coast of Georgia and southern South Carolina on Monday, move inland over eastern North Carolina Monday night and move along the coast of the mid-Atlantic states on Tuesday,” according to the hurricane centre.

A Tropical Storm Watch has been extended northward to Watch Hill, Rhode Island, including the Chesapeake Bay, Delaware Bay, Long Island and Long Island Sound.

Isaias already has caused destruction in the Caribbean: On Thursday, before it became a hurricane, it uprooted trees, destroyed crops and homes and caused widespread flooding and small landslides in the Dominican Republic and Puerto Rico. 

One man died in the Dominican Republic. In Puerto Rico, the National Guard rescued at least 35 people from floods that swept away one woman, whose body was recovered Saturday.

Isaias snapped trees and knocked out power as it blew through the Bahamas on Saturday.

With coronavirus cases surging in Florida recently, the added menace of a storm ratcheted up the anxiety. State-run virus testing sites closed in areas where the storm might hit because the sites are outdoor tents, which could topple in high winds.

Natalie Betancur, stocking up at a grocery in Palm Beach Gardens, said that the storm itself doesn't cause her a great amount of concern.

“The hurricane is not that serious, but I feel that the public is really panicking because it’s a hurricane and we’re in the middle of a pandemic," she said.

Officials in the Bahamas opened shelters for people in Abaco island to help those who have been living in temporary structures since Dorian devastated the area, killing at least 70 people in September 2019.
