DISCUSSION
A VERY EARLY SUMMER LIKE WEATHER SET UP WILL KEEP A PERSISTENT SOUTH-
SOUTHEAST FLOW OF 10 TO 15 KNOTS IN PLACE THROUGH THE MIDDLE OF NEXT
WEEK. SEAS WILL REMAIN WELL BELOW ANY HAZARDOUS LIMITS AT 1 TO 3
FEET THROUGH THE PERIOD. THE GREATEST CONCERN AND UNKNOWN IS ANY
SHOWER OR THUNDERSTORM IMPACTS. A SERIES OF DISTURBANCES WILL TRY TO
PRODUCE AN AREA OF STORMS OVER THE RED RIVER AREA AND THESE MAY MOVE
TOWARDS THE COASTAL WATERS BEFORE THEY DISSIPATE. IF THEY DEVELOP,
THESE SPECIFIC TYPE OF SYSTEMS NORMALLY DO NOT PLAY WELL WITH THE
MODELS AND THEY USUALLY SURGE SOUTHEAST FASTER AND STRONGER THAN
EXPECTED. IF THEY DO, EXPECT LOCALLY HIGHER WINDS AND SEAS AROUND
THESE STORMS. AFTERWARDS, WINDS MAY BECOME LIGHT AND VARIABLE FOR 3-
6 HOURS BEFORE THE SYNOPTIC SOUTH-SOUTHEAST WINDS TAKE BACK OVER.
