The US National Hurricane Centre in its 8 a.m. tropical storm update reported Tropical Storm Isaac's centre was 25 miles east of Dominica and 80 miles southeast of Guadeloupe. Effective at 8 p.m. Tuesday, the Coast Guard Sector San Juan captain of the port set port condition X-ray for the USVI and Puerto Rico due to the expectation of sustained gale force winds of 25 mph and gusts up to 40 mph generated by tropical storm Isaac that may arrive within 48 hours. Florence remains a unsafe Cat 4 with max winds of 130 miles per hour with a NW movement of 15 miles per hour.
This remarkable satellite image shows Hurricane Florence is one of just nine potentially unsafe storms now circling around the world.
The storm has become less organized over the eastern Caribbean with the latest advisory, as it continues on a westward path.
Hurricane Helene is heading north to open sea off the coast of the United States and now poses no danger to land after the storm hit cooler waters in the Atlantic.
It's a detail that almost got lost among all the wind, rain and storm surge data sent out by the National Hurricane Center on Wednesday.
The National Hurricane Center is predicting the storm will produce "catastrophic flash flooding and significant river flooding". Satellite images show very little left as a recognizable tropical storm. Current estimates have Isaac passing nearly 150 miles south of St. Croix early Friday morning. An average hurricane season includes at least 12 named storms. That funding can not be spent on disaster response, they said. It should dissipate by early next week, the hurricane center said. "Heed those warnings and evacuate if you're in one of the zones".
Acting Prime Minister Reginald Austrie told a news conference that while residents should not panic, they should nonetheless take all precautions to prevent a recurrence of the death and destruction caused by Maria when it slammed into the island on September 18.
Meanwhile, the projections for rain are growing, adding to growing concerns about flooding across the two states: Coastal North Carolina now expects 20-30 inches, with isolated areas of 40 inches projected in SC.
But looking further ahead, a spell of warmer and more settled weather has been forecast next week as high pressure lingering over Europe may keep storm systems from the Atlantic at bay. McNoldy says "the rainfall has been and continues to be a very substantial threat over the entire area". All lanes of Interstate 26 are westbound to allow more people to leave the coast and head inland toward the state capital of Columbia.
"The rain's going to be around for a long time", he said. This rainfall may cause risky flash flooding, N.H.C. said.
