Leaders urged caution in the Bahamas, where many people are still living in tents from last year's strike by Hurricane Dorian. Prime Minister Hubert Minnis announced he was relaxing a COVID-19 lockdown as the storm approached, but said a 10 p.m. to 5 a.m. curfew would be implemented starting Friday.
"I beg you, do not use this period for hurricane preparation to go socializing and visiting friends or family," Minnis wrote on Twitter. "If you do not need to be out, please, please, STAY AT HOME! We are in the midst of a pandemic and if we do not act responsibly, the consequences could be dire."
As Isaias passed over Puerto Rico and the Dominican Republic over the past two days, having not yet reached hurricane strength, it toppled trees, destroyed crops, knocked out power, produced widespread flooding and caused small landslides.
A man died in the Dominican Republic when he was electrocuted by a fallen electrical cable.
The Puerto Rico National Guard rescued at least 35 people from floodwaters, which swept away one woman who remains missing.
Another storm to watch
The National Hurricane Center was also monitoring an area of low pressure that may develop into a tropical cyclone, a rotating storm systems that could strengthen into a tropical storm or hurricane.
Located just east of the Caribbean, it has 60% chance of forming over the next five days and is projected to head northwest and then north.
Another system off the African coast became Tropical Depression No. 10 Friday night but then dissipated Saturday.
The next storm to get a name this season will be called Josephine.
A busy 2020 hurricane season
There have been four other tropical storms so far this month: Edouard, Fay, Gonzalo and Hanna. Other named storms this year have included Arthur, Bertha, Cristobal and Dolly. Tropical Storm Arthur formed in mid-May, making this the sixth straight year that a named storm formed before the official start of hurricane season on June 1.
So far, Hanna has been the only other hurricane of the season, striking Texas late last week as a strong Category 1 storm.
Virtually all estimates for this hurricane season predict an above-average number of storms, due to unusually warm ocean temperatures and global climate factors that are likely to reduce the high-altitude winds that can prevent the formation of hurricanes. On July 8, Colorado State University issued a slightly more pessimistic outlook for hurricane season than its earlier forecast, upping the number of named storms from 19 to 20.
