MARINE WEATHER HF VOICE BROADCAST FOR THE TROPICAL N ATLANTIC
FROM 07N TO 19N W OF 55W, THE N ATLANTIC FROM 19N TO
31N W OF 55W INCLUDING THE BAHAMAS, AND THE CARIBBEAN SEA.

SYNOPSIS FOR CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM
07N TO 19N W OF 55W
SYNOPSIS
HURRICANE ERIN IS N OF AREA NEAR 26.6N 72.7W AT 5 PM
EDT, AND IS MOVING NORTH-NORTHWEST AT 9 KT. MAXIMUM SUSTAINED
WINDS ARE 90 KT WITH GUSTS TO 110 KT, AND THE MINIMUM CENTRAL
PRESSURE IS 958 MB. AS ERIN CONTINUES TO LIFT NORTHWARD AWAY
FROM THE REGION, THE NORMAL TRADE WIND FLOW WILL COME BACK ON
WED. WINDS WILL ALSO INCREASE TO FRESH TO STRONG SPEEDS ACROSS
THE SOUTH-CENTRAL CARIBBEAN WED EVENING THROUGH FRI AS HIGH
PRESSURE BUILDS IN THE WAKE OF ERIN. A TROPICAL WAVE LOCATED
OVER THE CENTRAL TROPICAL ATLANTIC CONTINUES TO PRODUCE A BROAD
AREA OF DISORGANIZED SHOWERS AND THUNDERSTORMS. ENVIRONMENTAL
CONDITIONS APPEAR CONDUCIVE FOR GRADUAL DEVELOPMENT OF THIS
SYSTEM, AND A TROPICAL DEPRESSION COULD FORM TOWARD THE END OF
THE WEEK OR THIS WEEKEND. THIS SYSTEM SHOULD MOVE WESTWARD TO
WEST-NORTHWESTWARD AT 15 TO 20 KT AND APPROACH THE VICINITY OF
THE NORTHERN LEEWARD ISLANDS ON FRIDAY.
