NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT SUN JUL 18 2010

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

1. A TROPICAL WAVE IN THE VICINITY OF THE LEEWARD ISLANDS CONTINUES TO
PRODUCE DISORGANIZED SHOWERS AND THUNDERSTORMS.  ALTHOUGH SURFACE
PRESSURES HAVE FALLEN SLIGHTLY OVER THE AREA...ANY DEVELOPMENT OF
THIS DISTURBANCE IS LIKELY TO BE SLOW TO OCCUR AS IT MOVES WEST-
NORTHWESTWARD AT ABOUT 15 MPH.  THERE IS A LOW CHANCE...10
PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS.  REGARDLESS OF DEVELOPMENT...GUSTY WINDS AND LOCALLY
HEAVY RAINFALL ASSOCIATED WITH THIS SYSTEM COULD AFFECT THE LEEWARD
ISLANDS...THE VIRGIN ISLANDS...PUERTO RICO...THE DOMINICAN
REPUBLIC...HAITI...AND THE TURKS AND CAICOS ISLANDS DURING THE NEXT
COUPLE OF DAYS.

2. ANOTHER TROPICAL WAVE IS PRODUCING SHOWERS AND THUNDERSTORMS OVER
PORTIONS OF THE CENTRAL CARIBBEAN SEA.  THERE ARE NO SIGNS OF A
SURFACE CIRCULATION IN THIS AREA AND DEVELOPMENT...IF ANY...OF THIS
DISTURBANCE SHOULD BE SLOW TO OCCUR AS IT MOVES GENERALLY WESTWARD
AT 10 TO 15 MPH.  THERE IS A LOW CHANCE...10 PERCENT...OF THIS
SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
