The radar

The Charleston,SC radar (KCLX), 38 km from the middle of the area, began a volume at 18:11 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Charleston AFB, SC (KCHS), launched 12:00Z, 6.1 hours before the alert went out and 84 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

NATIONAL WEATHER SERVICE CHARLESTON SC
1011 AM EDT THU OCT 6 2005

.SHORT TERM /THIS AFTERNOON/...TAMMY WILL BE DOWNGRADED TO A
DEPRESSION AT 11 AM...AND IS LOCATED OVER SOUTHWEST GEORGIA. BANDS
OF RAIN CONTINUE TO ROTATE ON SHORE THIS MORNING AND EXPECT THIS
TREND TO CONTINUE THROUGH THE AFTERNOON HOURS. HEAVY RAINFALL OVER
THE PAST FEW DAYS HAS LEFT CWFA SATURATED. OUR WESTERN GEORGIA
COUNTIES WILL CATCH A BREAK THIS AFTERNOON BUT CAN NOT RULE OUT
REDEVELOPMENT THERE. HOWEVER...THE MAIN FOCUS FOR HEAVY RAIN THIS
AFTERNOON SHOULD BE ALONG AND NORTHEAST OF THE SAVANNAH RIVER. WILL
CONTINUE HIGH POPS FOR SOUTH CAROLINA ZONES BUT TRIM THEM BACK SOME
IN GEORGIA. WILL KEEP FLOOD WATCH FOR THE AFTERNOON AND WILL HAVE TO
MAKE DECISION THIS AFTERNOON ON WHETHER TO EXTEND IT.

NOW THAT THE TROPICAL STORM WARNING HAS BEEN DROPPED...WILL HAVE TO
CONSIDER A HIGH SURF ADVISORY. SEAS AT BOTH GRAYS REEF AND THE
GEORGIA TECH SAVANNAH BUOY ARE FALLING SO WILL NOT ISSUE ADVISORY
FOR GEORGIA COAST. THE CHARLESTON PILOT BOAT REPORTED 8 TO 12 FEET
SEAS A FEW MILES OFF THE COAST THIS MORNING SO WILL ISSUE AN
ADVISORY FOR THE SOUTH CAROLINA WATERS.

REMNANT T.D. CAN BE SEEN ON VISIBLE SAT AS A CLEAR PATCH NOW
APPROACHING KSAV. THIS SHOULD ONLY BE TEMPORARY WITH ANOTHER SCT TO
BKN DECK MOVING IN FROM THE SW AHEAD OF A POTENT S/W FEATURE. BEST
CHANCE OF THUNDER WILL BE AT KSAV WHERE MORE INSTABILITY COULD
DEVELOP. CIGS WILL GENERALLY BE MVFR AT BOTH TERMINALS THROUGH THE
DAY WITH VFR VSBYS FOR ALL BUT THE HEAVIEST SHOWER ACTIVITY.

&&

.RIP CURRENTS...SINCE THE TROPICAL STORM WARNING IS BEING DROPPED
