EVACUATING IF YOU LIVE IN A METAL ROOF OR CONTAINER HOME, AND DO
SO IF ORDERED BY LOCAL OFFICIALS.
..WIND INFORMATION
TROPICAL STORM FORCE WINDS OF 40 TO 50 MPH ARE ONLY POSSIBLE IF
THERE IS A SIGNIFICANT WESTWARD SHIFT IN THE TRACK OF TROPICAL STORM
SAUDEL TODAY OR TONIGHT. OTHERWISE, PERSISTENT SOUTHWESTERLY MONSOON
MAY CONTINUE TO BRING NEAR HAZARDOUS CONDITIONS UP TO 38 MPH AS
SAUDEL INTENSIFIES INTO A TYPHOON AND MOVES OVER THE FAR NORTHERN
MARIANAS.
..COASTAL INUNDATION AND SURF INFORMATION
SURF WILL QUICKLY BUILD TO HAZARDOUS LEVELS, ESPECIALLY ALONG
NORTHERN AND EASTERN EXPOSURES OF TINIAN AND SAIPAN. SURF MAY
REACH DANGEROUS LEVELS OF 8 TO 12 FEET ALONG EAST-FACING REEFS
LATE TONIGHT OR SATURDAY MORNING, TO THEN SLOWLY SUBSIDE COMING
INTO EARLY NEXT WEEK. DURING PASSAGE, SIGNIFICANT COASTAL EROSION
AND POTENTIALLY SOME MINOR INUNDATION IS POSSIBLE ALONG EASTERN
AND NORTHERN EXPOSURES OF TINIAN AND SAIPAN.
..OTHER STORM EFFECTS
AS THE SOUTHWESTERLY MONSOON FLOW DEVELOPS AND STRENGTHENS OVER THE
WEEKEND, LOCALLY HEAVY RAINFALL WILL DEVELOP. RAINFALL TOTALS OF 1 TO
3 INCHES, WITH LOCALLY HIGHER AMOUNTS, ARE POSSIBLE. ADDITIONAL
RAINFALL IS EXPECTED NEXT WEEK. ADDITIONALLY, SURF AND SWELL WILL
INCREASE, WITH ELEVATED SURF LEVELS PROBABLE FOR SOUTH AND WEST

EARLY SATURDAY MORNING. DEPENDING ON HOW CLOSE THE CENTER OF SAUDEL
COMES, IT COULD BUILD INTO THE 15 TO 20 FOOT RANGE ALONG THE EAST
REEFS AT THAT TIME, AND THIS WOULD ELEVATE SURF ALONG OTHER REEFS AS
WELL. INUNDATION HEIGHTS OF 1 TO 3 FEET COULD CREATE SOME SIGNIFICANT
COASTAL EROSION, WITH THE HIGHEST POTENTIAL OCCURRING
DURING SAUDEL'S CLOSEST APPROACH SATURDAY.
OTHER STORM EFFECTS
AS SAUDEL CONTINUES TO INTENSIFY AND EVENTUALLY BECOME A TYPHOON
PRIOR TO MOVING ACROSS THE FAR NORTHERN MARIANAS, WIDESPREAD LOCALLY
HEAVY SHOWERS COULD DUMP 8 TO 12 INCHES OF RAIN ACROSS MUCH OF THE
AREA BY SUNDAY. DURING PEAK INTENSITY, UPWARDS OF 20 INCHES OF RAIN
