ALAMAGAN. DAMAGING WINDS ARE EITHER IMMINENT OR ALREADY OCCURRING.
PRECAUTIONARY/PREPAREDNESS ACTIONS
REMAIN IN SUITABLE SHELTER, SUCH AS A HARDENED STRUCTURE OR CAVE,

..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 ALREADY 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 THROUGH SUNDAY AFTERNOON, PASSING TO THE WEST OF MAUG
SATURDAY NIGHT, THEN TURNING SLIGHTLY TOWARDS THE NORTH SUNDAY
NIGHT. THE PASSAGE OF KROSA WEST OF THE ISLANDS WILL CAUSE SOUTHEAST
WINDS TO SHIFT MORE SOUTHERLY TODAY, WITH WIDESPREAD LOCALLY HEAVY
SHOWERS. LATEST FORECAST PROJECTIONS SHOW SOUTHERLY TROPICAL STORM
WINDS OF 40 TO 50 MPH ARE IMMINENT OR OCCURRING AT AGRIHAN, PAGAN
AND ALAMAGAN, GRADUALLY SHIFTING FROM SOUTH TO SOUTHWEST TODAY, THEN
REMAINING OUT OF THE SOUTHWEST AS WINDS DIMINISH THROUGH SUNDAY.
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
SURF WILL CONTINUE TO RISE ALONG SOUTH AND WEST FACING REEFS TODAY,
WELL EXCEEDING HAZARDOUS LEVELS OF 9 FT. SURF ALONG THESE WINDWARD
SHORES EXCEEDING DANGEROUS LEVELS OF 15 FT ARE EXPECTED TODAY BEFORE
PEAKING AT 15 TO 20 FT TONIGHT. SURF WILL BEGIN TO SUBSIDE SUNDAY,
POSSIBLY FALLING BELOW DANGEROUS LEVELS BY SUNDAY NIGHT. SURF 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.
