..WIND INFORMATION
AS SUPER TYPHOON SINLAKU (04W) CONTINUES TO MOVE CLOSER, THE THREAT
FOR SUSTAINED HIGH WINDS WILL INCREASE. NORTH TO NORTHEAST TROPICAL
STORM FORCE WINDS OF 35 TO 45 MPH ARE CURRENTLY FORECAST TO BEGIN
AFFECTING GUAM THIS EVENING OR TONIGHT, ESPECIALLY NEAR THE NORTHERN
COASTAL WATERS AND SHORES OF GUAM COMING INTO TUESDAY. THE LATEST
FORECAST HAS SHIFTED THE TRACK SLIGHTLY SOUTH PASSING NEAR OR OVER
TINIAN, BUT STILL LIKELY KEEPING STRONG TROPICAL STORM WINDS AROUND
60 MPH JUST NORTH OF GUAM. TROPICAL STORM FORCE WINDS AROUND 40 TO 50
MPH AND GUSTS TO 65 MPH ARE POSSIBLE INTO LATE TUESDAY EVENING AS
WINDS SHIFT TOWARDS THE NORTHWEST AND THEN WEST. TROPICAL STORM FORCE
WINDS ARE CURRENTLY FORECAST TO CONTINUE INTO EARLY WEDNESDAY.
..COASTAL INUNDATION AND SURF INFORMATION
DUE TO HIGHER ASTRONOMICAL TIDES THIS WEEK AND PRE-EXISTING ELEVATED
SEAS, DANGEROUS SURF IS EXPECTED OR ALREADY OCCURRING ACROSS NORTH,
EAST AND SOUTH REEFS IN THE MARIANAS AS SURF BUILDS TO AROUND 12
TO 16 FEET, AND POTENTIALLY SPREADING TO WEST FACING REEFS ONCE
STY SINLAKU MOVES WEST OF THE ISLANDS IN THE NEXT FEW DAYS. THE
MORE NORTHERN TREK OF SINLAKU COULD HELP TO LIMIT THE PEAK OF
COASTAL INUNDATION BUT INUNDATION OF 1 TO 3 FT IS STILL POSSIBLE
AS SURF AND WIND DRIVEN WAVES INCREASE AS TROPICAL STORM FORCE
WINDS ARRIVE; AS SUCH, A COASTAL FLOOD WATCH REMAINS IN EFFECT.
INLAND FLOODING MADE WORSE BY DEVELOPING RAIN BANDS DURING STORM
PASSAGE WILL SIGNIFICANTLY INCREASE COASTAL INUNDATION AS RAIN
RUN-OFF AND STORM SURGE INTERACT. SURF WILL BE SLOW TO DECREASE
AFTER SINLAKU'S EXIT TO THE NORTH-NORTHWEST IN THE SECOND HALF OF
THE WEEK, AS SWELLS WILL CONTINUE TO PUMMEL WESTERN MARIANAS SHORES.
..OTHER STORM EFFECTS
HEAVY, INTENSE RAINFALL WITH STY SINLAKU IS NOW LIKELY, AS QUICK-
MOVING NORTHEASTERLY SHOWERS ARE MAKING THEIR WAY ACROSS THE AREA AND
WILL CONTINUE TO DO SO THROUGH AT LEAST WEDNESDAY, WITH RAINFALL
AMOUNTS UPWARDS OF 15 TO 25 INCHES NEAR THE CENTER, AS THE SYSTEM
CROSSES THE MARIANAS. THE EXACT TRACK OF SINLAKU WILL DETERMINE WHERE
THE HEAVIEST RAINFALL WILL SET UP ACROSS THE ISLANDS. THE MORE
NORTHERN TRACK CURRENTLY FORECAST WILL LIKELY SHIFT THIS HEAVIER
RAINFALL NORTH OF GUAM, BUT 6 TO 12 INCHES OF RAINFALL ARE STILL
POSSIBLE. AS SUCH, A FLOOD WATCH REMAINS IN EFFECT FOR GUAM. SEE
LATEST FORECAST FOR LATEST INFORMATION. LISTEN FOR POSSIBLE FLASH
FLOOD WARNINGS FOR YOUR LOCATION, AND BE READY TO ACT IF FLASH
FLOODING DEVELOPS.

AS SUPER TYPHOON SINLAKU (04W) MOVES CLOSER, THE THREAT FOR SUSTAINED
HIGH WINDS WILL CONTINUE TO INCREASE. THE LATEST FORECAST IS FOR
TROPICAL STORM FORCE WINDS TO BEGIN AFFECTING ROTA, TINIAN AND
SAIPAN THIS EVENING OR TONIGHT, WITH TYPHOON FORCE WINDS DEVELOPING
TUESDAY. THE RECENT STORM TRACKS HAVE MAINTAINED A NORTHWARD PASSAGE
OF STY SINLAKU AS IT MOVES INTO THE MARIANAS AS A CATEGORY 4 OR 5
TYPHOON, PASSING NEAR OR ACROSS TINIAN AND SAIPAN.
FOR ROTA, IF THIS TRACK HOLDS, THE RISK FOR TYPHOON FORCE WINDS OF
75 MPH OR GREATER MAY DIMINISH. FOR NOW THE FORECAST HAS
NORTHERLY TROPICAL STORM WINDS AROUND 40 TO 50 MPH, EXPECTED TO
BECOME NORTHWEST TO WEST AND INCREASING TO 55 TO 65 MPH WITH GUSTS
TO 80 MPH TUESDAY WITH THE POTENTIAL FOR TYPHOON FORCE WINDS OF
AROUND 75 MPH POSSIBLE. TROPICAL STORM WINDS ARE EXPECTED TO
CONTINUE INTO WEDNESDAY AS WINDS SHIFT TO THE SOUTHWEST.
FOR TINIAN AND SAIPAN, THE CURRENT TRACK HAS SINLAKU PASSING NEAR OR
DIRECTLY OVERHEAD TUESDAY THROUGH TUESDAY NIGHT. THIS IS
FORECASTED TO BRING WINDS AROUND 130 TO 150 MPH WITH GUSTS TO 180
MPH POSSIBLE. DEVASTATING DAMAGE IS POSSIBLE IF THIS FORECAST
TRACK AND WIND SPEED HOLDS. AIRBORNE DEBRIS WILL CAUSE EXTENSIVE
DAMAGE. PERSONS, PETS, AND LIVESTOCK STRUCK BY THE WIND BLOWN
DEBRIS WILL BE INJURED OR KILLED. NEARLY ALL METAL ROOF HOMES WILL
BE DESTROYED. ELECTRICITY AND WATER WILL BE UNAVAILABLE FOR DAYS

WEST FACING REEFS ONCE STY SINLAKU MOVES WEST OF THE ISLANDS. SURF
AT ROTA IS EXPECTED TO BUILD TO AROUND 15 TO 20 FEET, AND 18 TO 25 FT
AT TINIAN AND SAIPAN. A MORE NORTHERN TRACK OF SINLAKU COULD HELP TO
LIMIT THE PEAK OF COASTAL INUNDATION AT ROTA, BUT INUNDATION OF AT
LEAST 3-5 FEET IS STILL POSSIBLE AS SURF AND WIND DRIVEN WAVES
INCREASE AS TROPICAL STORM FORCE WINDS ARRIVE. FOR TINIAN AND
SAIPAN INUNDATION OF OF AT LEAST 5-8 FEET IS POSSIBLE, ESPECIALLY
ALONG WINDWARD FACING BEACHES AND REEFS. A COASTAL FLOOD WATCH
REMAINS IN EFFECT. INLAND FLOODING MADE WORSE BY DEVELOPING RAIN
BANDS DURING STORM PASSAGE WILL SIGNIFICANTLY INCREASE COASTAL
INUNDATION AS RAIN RUN-OFF AND STORM SURGE INTERACT. SURF WILL BE
SLOW TO DECREASE AFTER SINLAKU'S EXIT TO THE NORTHWEST IN THE
SECOND HALF OF THE WEEK, AS SWELLS WILL CONTINUE TO PUMMEL WESTERN
MARIANAS SHORES.
..OTHER STORM EFFECTS
HEAVY, INTENSE RAINFALL WITH STY SINLAKU IS LIKELY FOR MUCH OF
THE WEEK, WITH MICROWAVE SATELLITE RAINFALL ESTIMATES SHOWING
AMOUNTS UPWARDS OF 15 TO 25 INCHES NEAR THE CENTER. THE MORE
NORTHERN TRACK CURRENTLY FORECASTED WILL LIKELY SHIFT THIS HEAVIER
RAINFALL OVER TINIAN AND SAIPAN, BUT 10 TO 20 INCHES OF RAINFALL
ARE STILL POSSIBLE FOR ROTA. THE EXACT TRACK OF SINLAKU WILL
DETERMINE WHERE THE HEAVIEST RAINFALL WILL SET UP ACROSS THE
ISLANDS. AS SUCH, A FLOOD WATCH REMAINS IN EFFECT FOR ROTA,
