..SMALL CRAFT ADVISORY WILL EXPIRE AT 5 PM CHST THIS AFTERNOON
WINDS HAVE BEEN BELOW 22 KT FOR THE LAST 24 HOURS AND SEAS ACCORDING
TO LATEST BUOY AND ALTIMETRY DATA ARE BELOW 10 FEET THIS AFTERNOON.
THIS SUPPORTS ALLOWING THE SMALL CRAFT ADVISORY TO EXPIRE. SEAS
WILL REMAIN ELEVATED, HOWEVER, DUE TO THE EAST SWELL GENERATED BY
THE TRADE-WIND SURGE TO THE EAST. AS INVEST 90W, CURRENTLY NEAR
POHNPEI, SLOWLY DEVELOPS AND MOVES NORTHWEST, THIS WILL STRENGTHEN
THE EAST SWELL AND SLOWLY INCREASE WINDS NEAR THE MARIANAS. THIS MAY
BRING HAZARDOUS CONDITIONS TO SMALL CRAFT TO THE MARIANAS LATER THIS
WEEK OR THIS WEEKEND.
