Small Craft Advisory 216, NWS Anchorage, AK

AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
300 PM AST MON MAR 6 2006

.DISCUSSION...TODAYS SATELLITE IMAGERY SHOWS A SMALL BUT TIGHTLY
WOUND LOW SOUTHEAST OF MIDDLETON ISLAND. THIS LOW WILL SLOWLY WEAKEN
AND DRIFT TO NEAR SEWARD BEFORE IT DISSIPATES TUESDAY NIGHT.
A WEAK LOW WEST OF THE PRIBILOF ISLANDS IS BRINGING SNOW SHOWERS INTO
THAT AREA THIS AFTERNOON. THIS LOW WILL DISSIPATE NEAR BRISTOL BAY
TUE MORNING.
THE MOST PROMINENT FEATURE HOWEVER IS THE STRONG JET THAT EXTENDS
FROM 40N 170W AND HEADS NORTHEAST TO JUST SOUTH OF THE ALASKA
PENINSULA AND KODIAK ISLAND. THIS JET IS RIDING UP A LARGE RIDGE IN
THE NORTH PACIFIC AND IS BEING SQUEEZED ON THE NORTHWEST BY COLD AIR.
THIS JET WILL FLATTEN OUT BY WEDNESDAY AS IT HELPS TO DEVELOP A
SIGNIFICANT LOW IN THE GULF OF ALASKA TUESDAY NIGHT AND WEDNESDAY.
THIS LOW WILL BECOME THE MAJOR WEATHER FOCUS FOR THE MIDDLE OF THIS
WEEK. EXPECT STRONG WINDS TO DEVELOP ALONG THE GULF COAST AS THE COLD
ADVECTION TO THE WEST OF THIS LOW WILL ENHANCE THE TIGHT PRESSURE
GRADIENT PRODUCED BY IT.

ALSO OF NOTE IS A MODERATE LOW NEAR THE SOUTHERN TIP OF KAMCHATKA
THIS AFTERNOON. THIS LOW WILL MOVE INTO THE WESTERN BERING SEA
TUESDAY NIGHT AND THEN SLOWLY WEAKEN AS A NEW LOW DEVELOPS IN THE
WESTERN ALEUTIANS ALONG THE WEATHER FRONT WEDNESDAY NIGHT.

MODELS IS RELATIVELY GOOD AGREEMENT. NO SIGNIFICANT DIFFERENCES TO
ADDRESS.
