Upper level trough to bring low level moisture; rip current risk for St. Croix

SAN JUAN — An upper trough and associated induced low level trough just northeast of the region will approach the area today through Monday increasing low level moisture.

Hot, hazy and humid conditions may produce maximum heat indices between 100 and 111 degrees or slightly higher in isolated areas in the west and northwest coastal and urban areas.

Late morning showers possible along the north and east coastal areas, followed by afternoon convection mainly over the central interior and west to southwest sections of Puerto Rico.

For today and tonight there is a moderate risk of rip currents for the coastlines of northwestern to north-central Puerto Rico, as well as for the eastern half of St. Croix. Low risk elsewhere.

No tropical cyclone formation is expected over the next seven days.
