MPH.

NORTHEAST WITH AN INCREASE IN FORWARD SPEED THROUGH SUNDAY, REMAINING

WINDS AT AGRIHAN, PAGAN, AND ALAMAGAN. DAMAGING WINDS ARE EITHER
IMMINENT OR ALREADY OCCURRING.

..AGRIHAN...PAGAN AND ALAMAGAN
..A TROPICAL STORM WARNING REMAINS IN EFFECT
PRECAUTIONARY/PREPAREDNESS ACTIONS
REMAIN IN A SUITABLE HARDENED SHELTER, IDEALLY A CONCRETE STRUCTURE
OR CAVE. SUFFICIENT FOOD AND WATER FOR EACH PERSON FOR A DAY OR TWO
SHOULD BE AVAILABLE, BECAUSE A MONSOON SURGE IS LIKELY TO CONTINUE
FOR A WHILE AFTER TROPICAL STORM KROSA HAS PASSED.
WIND INFORMATION
THE LATEST FORECAST TRACK SHOWS KROSA TURNING GENERALLY NORTH-
NORTHEASTWARD, PASSING TO THE WEST OF MAUG LATE SATURDAY NIGHT, THEN
TURNING SLIGHTLY TOWARDS THE NORTH SUNDAY NIGHT. LATEST FORECAST
PROJECTIONS SHOW SOUTHERLY TROPICAL STORM WINDS OF 40 TO 50 MPH ARE
IMMINENT OR OCCURRING AT AGRIHAN, PAGAN AND ALAMAGAN. WINDS WILL
GRADUALLY SHIFT FROM SOUTH TO SOUTHWEST TODAY AS KROSA PASSES WEST
OF THE ISLANDS, THEN REMAIN OUT OF THE SOUTHWEST AS WIND SPEEDS
BEGIN TO DIMINISH NEAR THE ISLANDS SUNDAY. WIDESPREAD LOCALLY HEAVY
SHOWERS WILL BRING FREQUENT STRONGER GUSTS. FOR ISLANDS FURTHER TO
THE NORTH, INCLUDING AGRIHAN, STRONG TROPICAL STORM FORCE WINDS OF 50
TO 60 MPH WILL BE POSSIBLE AT TIMES THROUGH EARLY SUNDAY MORNING.
AFTER THE PASSAGE OF TS KROSA, A STRONG SOUTHWEST MONSOON PATTERN
WILL PROLONG WINDY CONDITIONS THROUGH SUNDAY NIGHT.
COASTAL INUNDATION AND SURF INFORMATION
DANGEROUS SURF ALONG SOUTH AND WEST FACING REEFS WILL CONTINUE TO
RISE THIS AFTERNOON, WITH SURF HEIGHTS AROUND 15 FT EXPECTED TO
INCREASE FURTHER TO BETWEEN 15 AND 20 FT THROUGH TONIGHT. SURF WILL
BEGIN TO SUBSIDE SUNDAY, POSSIBLY FALLING BELOW DANGEROUS LEVELS BY
SUNDAY NIGHT. SURF ALONG SOUTH AND WEST FACING REEFS WILL LIKELY
REMAIN AT HAZARDOUS LEVELS OF 10 TO 14 FEET INTO EARLY NEXT WEEK DUE
TO THE PERSISTENT MONSOON FLOW. RIP CURRENTS DURING THIS TIME WILL BE
STRONG AND LIFE THREATENING. STAY OUT OF THE WATER. WIND AND WAVE-
DRIVEN COASTAL INUNDATION OF 3 TO 5 FT WILL BE LIKELY ALONG WINDWARD
SHORES, ESPECIALLY AROUND TIMES OF HIGH TIDE AS SURF REACHES PEAK
HEIGHTS THROUGH SUNDAY.
OTHER STORM EFFECTS
WIDESPREAD LOCALLY HEAVY SHOWERS WILL INCREASE THROUGH SUNDAY AS
TS KROSA PASSES TO THE WEST, WITH THE BULK OF RAINFALL EXPECTED
THROUGH TONIGHT. ADDITIONAL RAINFALL ACCUMULATIONS OF 4 TO 8 INCHES
ARE POSSIBLE THROUGH MONDAY. EVEN AFTER KROSA BEGINS TO MOVE AWAY
SUNDAY AND MONDAY, A WET MONSOON PATTERN WILL PROLONG SHOWERS ACROSS
THE ISLANDS.
