THE LATEST MODEL GUIDANCE INDICATES THAT AN INLAND LOW PRES TROF
CONTINUES TO COMBINE WITH A HIGH PRES RIDGE W OF THE PZ5 WATERS TO
PRODUCE NRLY WINDS UP TO 30 KT OR SO W OF POINT ST GEORGE. THESE
CONDITIONS WILL THEN SLOWLY DIMINISH TONIGHT AND WED. BY THU NIGHT

WATERS. BY THU NIGHT WEAK LOW PRES WILL MOVE SE INTO THE PZ5

WASHINGTON OFFSHORE WATERS AND PERSISTS INTO SUN.

THE LATEST GFS NOW BRINGS A RATHER POTENT LOW ACROSS THE PZ5
WATERS MON WHILE THE ECMWF JUST BRINGS A FRONT TOWARDS THE NRN
OFFSHORE WATERS WHILE HAVING A WEAKER LOW FARTHER S. THE LATEST
UKMET IS IN BETTER AGREEMENT WITH THE ECMWF AFTER 120 HOURS SO
