The National Weather Service is forecasting a warm, wet weekend for the Aleutians, Southcentral and Interior Alaska. Lead forecaster Bill Ludwig says a storm pulling air from the tropics is responsible.

“The reason it’s interesting is because of the long fetch of moisture coming up from the south and pushing into Alaska, so it’s pushing up very moist and warm air from very far south. And that’s a little bit unusual at this year time of year to get that kind of weather.”

The storm will bring high winds to Unalaska, with gusts of up to 65mph expected this evening. Temperatures will also climb throughout the day, peaking tomorrow in the low-40s. Meanwhile, in Anchorage and the Interior, temperatures could skyrocket from well below freezing into that range, possibly causing flooding. The storm system is expected to move through the Aleutians by Sunday.
