From the National Hurricane Center:

AT 1100 AM EDT…1500Z…THE CENTER OF TROPICAL STORM ERNESTO WAS
LOCATED NEAR LATITUDE 23.3 NORTH…LONGITUDE 79.5 WEST OR ABOUT 170
MILES…275 KM…EAST-SOUTHEAST OF KEY WEST FLORIDA AND ABOUT 180
MILES…285 KM…SOUTH-SOUTHEAST OF MIAMI FLORIDA.

ERNESTO IS MOVING TOWARD THE NORTHWEST NEAR 13 MPH…20 KM/HR…AND
THIS GENERAL MOTION IS EXPECTED TO CONTINUE TODAY AND TONIGHT. ON
THIS TRACK…THE CENTER WILL BE NEARING THE FLORIDA KEYS AND
EXTREME SOUTHERN FLORIDA TONIGHT. HOWEVER…RAINS AND SQUALLS WILL
BE ARRIVING WELL IN ADVANCE OF THE CENTER.

MAXIMUM SUSTAINED WINDS ARE NEAR 45 MPH…75 KM/HR…WITH HIGHER
GUSTS. SOME STRENGTHENING IS EXPECTED BEFORE THE CENTER REACHES
FLORIDA.

Hunkering Down is in progress.
