Winter Weather Advisory issued October 20 at 4:24AM AKDT until October 21 at 4:00AM AKDT by NWS Fairbanks AK, United States of America
Loading live data… · Marker positions are approximate; severity is labelled in each popup. Sources: USGS, GDACS, NASA EONET, NOAA/NWS, EMSC.
* WHAT...Snow expected. Total snow accumulations between 5 and 10
inches. Winds gusting as high as 35 mph.
* WHERE...Denali Borough.
* WHEN...Until 4 AM AKDT Wednesday.
* IMPACTS...Travel could be very difficult.
* ADDITIONAL DETAILS...North and west of Healy, the chance for heavy
snow drops off quickly due to a narrow gradient of snow. There is
potential for greater than 6 inches in Healy but only a few inches
in Anderson. The exact placement of the area of heavier will have a
dramatic effect on the final snowfall totals. If the band moves a
few dozen miles west, snowfall totals will be on the higher end of
the range, especially near Healy. If the band moves a few dozen
miles east, snowfall totals will likely be on the lower end, even
in Healy.
