The tropical wave near Puerto Rico, named Invest 90L, showed signs of hurricane development Sunday morning as it moved over the warm waters of the Caribbean Sea, the National Hurricane Center (NHC) in Miami said.
At this time, the system’s low pressure center is forecast to be off the island, but an extension of rain will reach Puerto Rico beginning this afternoon, mainly to the eastern and southern half of the city.
“Further development of this system is expected, and a tropical depression is likely to form during the first half of this week. The system is forecast to move westward or west-northwestward at 10 to 15 mph over the eastern and central Caribbean over the next few days, then turn northward by midweek.” Moving into the southwest Atlantic Ocean. Regardless of development, heavy rain is possible over parts of the Lesser Antilles over the next few days. Interests in the eastern and central Caribbean should monitor the system’s progress,” CNH said at 2:00 a.m. Sunday.
At 8:00 a.m. Sunday, the disturbance has a 70% chance of hurricane development within 48 hours and an 80% chance within seven days.
The National Weather Service in San Juan estimates that up to six inches of rain could fall on municipalities in eastern Puerto Rico during the wave’s effects.
“Lots of tropical moisture associated with INVEST 90L will gradually increase today (Sunday). Warmer conditions are expected before the onset of rain and thunderstorm activity,” they advanced.
“Ocean and coastal conditions will worsen with small craft advisories issued for the Caribbean Sea and local routes,” they add.
