PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE COLUMBIA SC
520 PM EDT WED JUN 06 2012

...FIRST MONTH OF ABOVE NORMAL RAINFALL THIS YEAR AT BOTH COLUMBIA
AND AUGUSTA...
...TROPICAL SEASON BEGINS EARLY WITH THE FORMATION OF ALBERTO AND
BERYL OFF THE SOUTHEAST COAST...
...ABOVE NORMAL TEMPERATURES CONTINUE THROUGH MAY...
...TIED FOR THE 10TH WARMEST MAY ON RECORD AT COLUMBIA...

FINALLY THE SKIES OPENED UP ACROSS THE MIDLANDS AND CENTRAL SAVANNAH
RIVER AREA AND ABOVE NORMAL RAINFALL FELL ACROSS NEARLY ALL OF THE
REGION. THE TREND OF ABOVE NORMAL TEMPERATURES DID CONTINUE ACROSS
THE REGION. LOOKING AT THE GLOBAL PATTERNS DURING THE MONTH OF
MAY...LA NINA IS OVER AND CURRENTLY NEUTRAL CONDITIONS HAVE RETURNED
TO THE CENTRAL AND EASTERN PACIFIC. THE NORTH ATLANTIC OSCILLATION
(NAO) REMAINED NEGATIVE TO NEARLY NEUTRAL FOR THE MONTH OF MAY. THE
DISSIPATION OF THE LA NINA AND THE NEGATIVE VALUES OF NAO LIKELY
COMBINED TO CREATE THE WETTER THAN NORMAL CONDITIONS ACROSS THE
REGION. THE WETTER THAN NORMAL WEATHER PATTERN ENDED A TREND OF
BELOW NORMAL MONTHLY PRECIPITATION AMOUNTS THAT HAVE PERSISTED FOR
ABOUT ONE YEAR. AT COLUMBIA METRO AIRPORT...THE LAST TIME THERE WAS
A MONTH WITH ABOVE NORMAL PRECIPITATION WAS JULY 2011. AT AUGUSTA
REGIONAL BUSH FIELD...THE LAST TIME THERE WAS A MONTH WITH ABOVE
NORMAL PRECIPITATION WAS MARCH 2011. THE JUNE OUTLOOK FROM THE
CLIMATE PREDICTION CENTER (CPC) IS FORECASTING EQUAL CHANGES. THIS
MEANS THAT THERE IS NO CLEAR SIGNAL FOR ABOVE...BELOW OR NORMAL
PRECIPITATION AMOUNTS FOR THE MONTH. THE FORECAST FOR TEMPERATURES
IS FOR A 33 PERCENT TO 40 PERCENT CHANCE OF ABOVE NORMAL
TEMPERATURES FOR JUNE. THE TROPICAL WEATHER OR HURRICANE
SEASON...WHICH BEGAN ON JUNE 1ST...GOT OFF TO A FAST START IN THE
ATLANTIC BASIN. THERE WERE TWO NAMES SYSTEMS DURING THE MONTH. THE
FIRST SYSTEM...TROPICAL STORM ALBERTO...FORMED ON THE 29TH AND
CONTINUED THROUGH THE 22ND. THE SYSTEM FORMED OFF THE SOUTH CAROLINA
AND GEORGIA COAST AND THEN MOVED NORTHEAST AWAY FROM THE COAST AND
WEAKENED. THE STORM PRODUCED STRONG WINDS ALONG AND OFFSHORE OF THE
CAROLINA COAST AS WELL AS DANGEROUS RIP CURRENTS. THE SECOND
SYSTEM...SUBTROPICAL STORM/TROPICAL STORM BERYL...FORMED ON THE 26TH
OFF THE COAST OF SOUTH CAROLINA EAST OF CHARLESTON. THE STORM
TRANSITIONED FROM SUBTROPICAL TO TROPICAL BEFORE COMING ASHORE NEAR
JACKSONVILLE FLORIDA JUST AFTER MIDNIGHT ON THE 28TH. THE STORM
WEAKENED TO A TROPICAL DEPRESSION SHORTLY THEREAFTER AND BECOME POST
TROPICAL ON MAY 30TH. WHEN BERYL REACHED THE FLORIDA COAST...HER MAX
WINDS WERE 70 MPH...IT WAS THE STRONGEST LANDFALL IN THE UNITED
STATE FOR ANY PRE-SEASON ATLANTIC TROPICAL SYSTEM ON RECORD. AS
BERYL MOVED ACROSS SOUTHEAST GEORGIA INTO THE LOWCOUNTRY OF SOUTH
CAROLINA...SHE PRODUCED HEAVY RAINFALL ACROSS THE EASTERN MIDLANDS
AND SOUTHEAST CENTRAL SAVANNAH RIVER AREA. RAINFALL AMOUNTS OF 3 TO
5 INCHES WERE COMMON IN THESE AREAS.
