ANCHORAGE, Alaska — A strong low pressure system will slowly pull into Bristol Bay today. Unlike the last couple of lows, this one is interacting with a jet streak, a localized area of strong winds along the jet stream. These strong winds aloft will combine with strong surface winds to transport abundant moisture out of the North Pacific into the state. This moist, warm southeasterly flow will cause inclement weather today before moving east into the Panhandle tomorrow.
Winds will gusts above 50 mph down Turnagain Arm and along the Upper Hillside of Anchorage today and tomorrow. Highs will be in the 40s. Strong SE flow will lead to heavy rain at times in PWS but only light, spotty showers in Anchorage and the Valley.
Watches and advisories abound around the state related to this storm system. Here is a breakdown:
-Winter Weather Advisory for the Middle and Lower Yukon and Lower Koyukuk Valleys until 6 pm tomorrow for snow and freezing rain: Up to half a foot of snow could fall over the Nulato Hills. As warmer air moves into the Interior at the mid-levels, there is a threat for light accumulations of freezing rain.
