STORM INFORMATION
AT 2 PM CHST, THE CENTER OF SUPER TYPHOON SINLAKU (04W) WAS
LOCATED BY PGUA RADAR NEAR LATITUDE 12.6N, LONGITUDE 148.2E. THIS

WEST-NORTHWEST, 300 DEGREES, AT 8 MPH. STORM INTENSITY WAS 180
MPH.
SITUATION OVERVIEW
SUPER TYPHOON SINLAKU (04W) CONTINUES TO MOVE WEST-NORTHWEST
TOWARD THE MARIANAS WITH A SLIGHT NORTHWEST TURN EXPECTED. THE
OUTER RAIN BANDS OF SINLAKU ARE BEGINNING TO ROTATE IN OVER THE
ISLANDS, AND CONTINUE TO BRING PERIODS OF HEAVY SHOWERS,
THUNDERSTORMS, AND STRONG WINDS FOR THE FAR OUTER ISLANDS OF
NORTHWEST CHUUK. HOWEVER, TROPICAL STORM WINDS OF 39 MPH OR
GREATER HAVE MOVED AWAY FROM ULUL. THE MOST RECENT STORM TRACK
PRODUCED BY THE JOINT TYPHOON WARNING CENTER (JTWC) HAS SHOWN A
SLIGHT NORTHWARD SHIFT IN THE STORM PATH DURING ITS PASSAGE TOWARD
THE MARIANAS, STILL MAINTAINING A TRACK NORTH OF ROTA AND NEAR OR
OVER TINIAN AND SAIPAN. SINLAKU IS EXPECTED TO GRADUALLY WEAKEN
THE NEXT FEW DAYS, BUT STILL EXPECTED TO CROSS THE MARIANAS AS A
CATEGORY 4 OR 5 TYPHOON.
PRECAUTIONARY/PREPAREDNESS ACTIONS
FOR THOSE UNDER A WARNING IN THE MARIANAS, THE WINDOW OF TIME TO
COMPLETE PREPARATIONS FOR THE PROTECTION OF LIFE AND PROPERTY IS
VERY SOON TO CLOSE. EVACUATE IF DIRECTED TO DO SO BY LOCAL

FLOODING.
FOR INTERESTS AT PORTS, DOCKS, AND MARINAS, URGENTLY COMPLETE
PRESCRIBED PREPARATIONS ACCORDING TO YOUR EMERGENCY OPERATIONS PLAN
FOR TROPICAL CYCLONES. IF YOU LIVE ON A BOAT, MAKE FINAL
PREPARATIONS FOR SECURING YOUR CRAFT BEFORE LEAVING IT. SMALL
CRAFT SHOULD REMAIN IN PORT AND WELL SECURED.
FOR THOSE UNDER A WATCH IN THE FAR NORTHERN MARIANA ISLANDS,
CONTINUE WITH YOUR PREPARATIONS AND LISTEN FOR POSSIBLE WARNINGS.
CLOSELY MONITOR NOAA WEATHER RADIO OR OTHER LOCAL NEWS OUTLETS
FOR OFFICIAL STORM INFORMATION. LISTEN FOR POSSIBLE CHANGES TO
THE FORECAST.
STAY INDOORS DURING HEAVY RAIN AND WINDY CONDITIONS ASSOCIATED WITH
SUPER TYPHOON SINLAKU (04W). THE ONSET OF DAMAGING, AND POTENTIALLY
DESTRUCTIVE WINDS, WILL POSE A DEADLY THREAT TO THOSE VENTURING

..TROPICAL STORM WARNING REMAINS IN EFFECT
..TYPHOON WATCH REMAINS IN EFFECT
..PRECAUTIONARY/PREPAREDNESS ACTIONS
THE WINDOW OF TIME TO COMPLETE PREPARATIONS FOR THE PROTECTION OF
LIFE AND PROPERTY IS VERY SOON TO CLOSE. ITEMS TO BRING TO A
SHELTER INCLUDE A FIRST AID KIT, MEDICINES AND PRESCRIPTIONS, BABY
FOOD AND DIAPERS, GAMES AND BOOKS, TOILETRIES, A BATTERY POWERED
RADIO, A CELL PHONE, FLASHLIGHTS WITH EXTRA BATTERIES, A BLANKET
OR SLEEPING BAG FOR EACH PERSON, PERSONAL IDENTIFICATION, COPIES
OF KEY PAPERS SUCH AS INSURANCE POLICIES, AVAILABLE CASH AND
CREDIT CARDS. REMEMBER, PETS ARE NOT ALLOWED IN MOST PUBLIC
SHELTERS, SO CHECK AHEAD WITH YOUR INTENDED SHELTER.
REGARDING YOUR HOME OR BUSINESS, FINISH COVERING ALL WINDOWS AND
DOORS WITH SHUTTERS OR PLYWOOD. MOVE PATIO FURNITURE AND OTHER LOOSE
OBJECTS INDOORS. BRACE ALL EXTERIOR DOORS, INCLUDING GARAGE DOORS.
STAY CALM AND KEEP INFORMED. COMPLY WITH ANY EVACUATION ORDERS THAT
ARE ISSUED FOR YOUR AREA. IF YOU LIVE IN A METAL ROOF OR CONTAINER
HOME, OR YOU LIVE IN A SURGE ZONE OR ANY LOCATION PRONE TO FLOODING,
EVACUATE TO A DESIGNATED SHELTER OR RIDE OUT THE STORM IN THE STURDY
HOME OF FAMILY OR FRIENDS OUTSIDE OF EVACUATION ZONES.
..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 NORTH PASSING NEAR OR
OVER SOUTHERN SAIPAN, 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 HEIGHTS BUILD 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 LIKELY, AS QUICK-
MOVING NORTH-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.

..WIND INFORMATION
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
AND PERHAPS WEEKS AFTER THE STORM PASSES. MOST TREES WILL BE
SNAPPED OR UPROOTED. FALLEN TREES MAY CUT OFF RESIDENTIAL AREAS
FOR DAYS TO WEEKS.
..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 AND POTENTIALLY SPREADING TO
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, AS QUICK-
MOVING NORTH-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 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
