SPECIAL TROPICAL DISTURBANCE STATEMENT
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
1125 AM EDT FRI JUL 18 2008

THIS STATEMENT CONCERNS TWO TROPICAL WEATHER SYSTEMS.

SATELLITE IMAGES INDICATE THAT THE AREA OF LOW PRESSURE LOCATED IN THE CENTRAL CARIBBEAN SEA ABOUT 400 MILES SOUTHEAST OF JAMAICA CONTINUES TO BECOME BETTER-ORGANIZED. AN AIR FORCE RESERVE UNIT RECONNAISSANCE AIRCRAFT IS SCHEDULED TO INVESTIGATE THIS SYSTEM THIS AFTERNOON TO DETERMINE IF A TROPICAL DEPRESSION OR TROPICAL STORM HAS FORMED. ALL INTERESTS IN THE CENTRAL AND WESTERN CARIBBEAN SEA SHOULD CONTINUE TO MONITOR THE PROGRESS OF THIS SYSTEM AS IT MOVES WESTWARD AT 15-20 MPH. FOR INFORMATION SPECIFIC TO YOUR AREA...PLEASE CONSULT STATEMENTS FROM YOUR LOCAL WEATHER OFFICE.

SURFACE OBSERVATIONS AND SATELLITE IMAGES INDICATE THAT A LOW PRESSURE SYSTEM LOCATED JUST OFF THE COASTS OF GEORGIA AND SOUTH CAROLINA IS ALSO BECOMING BETTER ORGANIZED. ENVIRONMENTAL CONDITIONS ARE CONDUCIVE FOR FURTHER DEVELOPMENT...AND A TROPICAL DEPRESSION COULD FORM TODAY OR TOMORROW. AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT IS SCHEDULED TO INVESTIGATE THIS SYSTEM TOMORROW...IF NECESSARY. ALL INTERESTS ALONG THE COASTS OF GEORGIA...SOUTH CAROLINA...AND NORTH CAROLINA SHOULD MONITOR THE PROGRESS OF THIS SYSTEM. LOCALLY HEAVY RAINFALL IS POSSIBLE IN THESE AREAS DURING THE NEXT COUPLE OF DAYS AS THIS SYSTEM MOVES SLOWLY NORTHEASTWARD NEAR THE COAST. FOR INFORMATION SPECIFIC TO YOUR AREA...PLEASE CONSULT STATEMENTS FROM YOUR LOCAL NATIONAL WEATHER SERVICE FORECAST OFFICE.

Both of them are blowing up nicely on satellite loops:
