SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)

** Wind Advisory for South Anchorage, the Anchorage Hillside and Turnagain Arm. **

** Flood Advisory is in effect for the Yentna River **

A series of low pressure systems will track through Southcentral through the end of this week bringing periods of rain and short- lived dry periods to the region. Steady rainfall, moderate to heavy at times, has persisted since early this morning across Southcentral Alaska. Rainfall amounts today through mid-afternoon range from 0.05" in the Western Kenai Peninsula to 0.27" in the Anchorage Bowl and Prince William Sound areas.

A low pressure system continues to move northward through the Kenai Peninsula this afternoon with the heaviest rainfall in the Prince William Sound to, eventually, Copper River Valley. In its wake, scattered showers then dryer conditions will prevail in the western Kenai Peninsula and portions of the Anchorage Bowl overnight through late Wednesday morning. However, rain continues in the Mat- Su Valleys, Prince William Sound and Copper River Basin through late this evening. Gusty southeasterly winds are expected through much this evening, especially for gap wind prone locations. Winds coming out of the Turnagain Arm will at times bend into Anchorage and southerly winds pushing into the Sound will also accelerate northward through the Copper River Basin. The recent rainfall has resulted in issuing a flood advisory for the Yentna River. Tomorrow's scattered showers will diminish through the day. Another low pressure brings rainfall to Southcentral Thursday.

AVIATION

PANC...Periods of rain will continue into tonight, then eventually let up by Wednesday morning as the front associated with a low moving over Southwest pushes past the terminal. Southeast winds that have mostly been staying to the south will briefly bend into town this evening, with a few gusts between 25 and 30 kts briefly possible. Any lingering threat for LLWS will quickly diminish as the winds at the surface pick up late this afternoon and evening. Winds will briefly weaken somewhat and turn out of the south later this evening, but will likely become gusty again late tonight into Wednesday morning. Ceilings could also lower into MVFR range once winds turn out of the south overnight tonight.
