As of 10 a.m. ET, the storm’s core was still moving over Puerto Rico, bringing “life-threatening wind, storm surge and rainfall,” the NHC reported. The area is still recovering from damage brought by Hurricane Irma.

After hitting Yabucoa, Hurricane Maria is expected to move over the Dominican Republic’s northeastern cost, then begin turning north. A hurricane warning is already in effect for the area, as well as for Turks and Caicos and the southeastern Bahamas.

The NHC’s forecast also noted that Maria may regather strength before hitting the Dominican Republic Thursday morning.
