It will get worse as the night progresses, according to meteorologist Jose Alamo at the National Weather Service in San Juan. As the Weather Service meteorologists indicated repeatedly, St. Croix will get more than St. Thomas and St. John, but all three islands can expect windy and rainy conditions.
“The wind gusts will be mainly happening with the showers,” Alamo said at 5:15 p.m. Wednesday.
Wind gusts will range from 35 to 40 mph on St. Croix, with the other two islands seeing gusts in the 30 to 35 mph range.
Rainfall will be heavy, with 4 to 6 inches falling across the territory between Wednesday afternoon and Friday. A flash flood watch was issued for the Virgin Islands.
The center of Isaac is expected to pass 80 miles south of St. Croix at around 7 a.m. Thursday, Alamo said. It will be 120 miles south of St. Thomas and 130 miles south of St. John around the same time.
The territory remains on a tropical storm warning and a hurricane watch. A hurricane watch means that hurricane force winds are possible.
The storm was centered at 16 degrees north latitude and 61.2 degrees west longitude, putting it 268 miles southeast of St. Croix.
The tropical storm force winds extend outward 80 miles from the center.
Isaac is moving west at 22 mph. The barometric pressure stands at 1004 millibars or 29.65 inches.
Further out in the Atlantic Ocean, Tropical Depression 10 got a number at the 11 a.m. update, but Alamo said that storm is expected to pass northeast of the northern Virgin Islands Sunday night into Monday.
Gov. John deJongh Jr. announced Wednesday that all government offices on St. Croix will close Thursday but those on St. Thomas and St. John will remain open. He said there was no need for a curfew.

In addition to the general population shelter at Herbert Grigg Home for the Aged on St. Croix, the Charles Harwood Medical Complex on St. Croix serves as a shelter for people needing medical assistance during an evacuation. Both will open at 7 p.m. Wednesday.
Special needs people are independent individuals with special medical support equipment needs or who receive care in the home from a family member, a press release indicated, suggesting that those individuals using the special needs shelter should bring medical equipment, such as oxygen tanks, if necessary and all medication and dietary supplies, as well as a caregiver.
