PERIODS OF HEAVY RAIN TONIGHT AND TUESDAY NIGHT.

A VIGOROUS AUTUMNAL STORM BEARS DOWN ON THE PACIFIC NORTHWEST LATE

SUNNY CONDITIONS AND BREEZE CONDITIONS ON TUESDAY IN ADVANCE OF

SUBSIDING THEREAFTER.  THE HIGHEST WINDS FROM THE SYSTEM SHOULD
REMAIN OFFSHORE THE PACIFIC NORTHWEST AND ALONG THE COAST OF
WESTERN BRITISH COLUMBIA AND VANCOUVER ISLAND.

FLORIDA AND THE IMMEDIATE SOUTHEAST COAST WILL BE WET AS A WEAK
WAVE OF LOW PRESSURE AND ITS ATTENDANT COASTAL TROUGH FOCUSES
THUNDERSTORMS WITH POTENTIALLY HEAVY RAINFALL TO THE EAST OF A
BUNDLE OF UPPER LEVEL ENERGY SLIDING INTO GEORGIA AND THE
CAROLINAS.

ELSEWHERE, THE GREAT LAKES, OHIO RIVER VALLEY, NORTHEAST, AND
MID-ATLANTIC STATES WILL BE SEASONABLY COOL UNDER THE AEGIS OF
