Marine Weather and Tide Forecast for Cordova, AK

.SHORT TERM FORECAST SOUTHWEST ALASKA AND BERING SEA/ALEUTIANS (Days 1 through 3)...

Scattered showers are moving across the Southwest mainland this morning while a low occupies Bristol Bay. The strongest winds will be diving down across the Alaska Peninsula peaking around 10AM AKST. Closer to 4PM AKST the low drops south of the AKPen and settles into the Souther Gulf. Almost simultaneously, a second low from the North Pacific enters into the western Bering near Attu. This second low tracks across the southern Bering and crosses back in to the North Pacific over Unalaska by Friday afternoon. Wind from this low will be weaker than its predecessor, and precipitation from this system is not expected to advance beyond the western Alaska Peninsula. Between these lows, an area of high pressure sweeps across the central Bering, arriving at the Southwest mainland by Thursday and persists into the weekend.

Ridging over the western mainland will bring warmer temperatures, and reduced cloud cover will give rise to convective showers.
This pattern should persist while the next system sweeps across the Bering sea Friday and Saturday. Widespread gales will be limited to the western and central Aleutians, however several bands of rain are anticipated to reach the mainland later in the weekend.

.LONG TERM FORECAST (Days 4 through 7: Saturday through Tuesday)...

A number of upper level low centers progress from the Russian Far East across the Bering and Alaska Peninsula into the Gulf of Alaska through the forecast period. Main jetstream energy remains across the North Pacific into the new week, with shortwaves passing through the pattern. Most of the active weather will be occurring over the Southern portions of the state. Ensemble forecast models handle the features overall with some variations in timing of individual events.

Lingering showers are expected over the Southern half of Mainland Alaska through the weekend. A well developed low and front pushing across the Western Aleutians and Bering brings moderate rain and locally gusty winds across the region. This front moves over the Central and Eastern Bering on into Western Alaska, the AKPEN and Kodiak Island Sunday before spreading across Southcentral Alaska through Tuesday. Locally moderate rain moves further into the Interior with the front extending across the coasts. The supporting surface low crosses the AKPEN Monday and slips South of Kodiak Island through Tuesday.
