A strong parade of storms has been making its way through the North Central Pacific Ocean, and the location of the jet stream has produced colder storms for Unalaska and the Aleutian region this year. That’s according to Rick Thoman, a climate specialist at the International Arctic Research Center with the University of Alaska Fairbanks.

Strong winds on the Alaska Peninsula Monday swept volcanic ash from a 1912 eruption across the region, triggering a SIGMET warning from the National Weather Service.

A meteorologist with the National Weather Service in Anchorage said a fairly strong low pressure system is traversing the Aleutians from West to East. Cold air, mixed with subtropical moisture, is leading to heavy snow and high winds.

The National Weather Service said Tuesday between 3 to 3.5 inches of rain had already fallen in the last 24 hours and that up to 5.5 inches were possible. The one-day total precipitation — 3.76 inches as of 10 a.m. Tuesday — ranks in the top-10 highest on record.
