MOVE INTO KODIAK ISLAND AND THE SOUTHERN KENAI PENINSULA THURSDAY
EVENING THEN INTO THE SUSITNA VALLEY AND PRINCE WILLIAM SOUND
THURSDAY NIGHT AND FRIDAY. INCREASING SOUTHEAST WINDS OVER THE
NORTHERN GULF AND THROUGH PRINCE WILLIAM SOUND WILL PRODUCE A RAIN
SHADOW OVER ANCHORAGE AND THE MATANUSKA VALLEY THURSDAY NIGHT AND

AND FRIDAY.

.SOUTHWEST ALASKA...RAIN WILL MOVE INTO THE KUSKOKWIM VALLEY AND
BRISTOL BAY WHILE A MIXTURE OF RAIN AND SNOW WILL FALL OVER THE
