Spot Forecast for SAR Tustumena Glacier...Alaska State Troopers

National Weather Service Anchorage AK

1137 AM AKDT Thu Apr 18 2024



Forecast is based on forecast start time of 1100 AKDT on April 18. 

.DISCUSSION...



Persistent conditions are expected to continue into Friday 

morning with snow and strong, gusty east to southeast winds. The 

strongest winds and precipitation is expected to be primarily 

during the day today near the spot location. Gusty winds across 

the mountains has allowing ceilings to be higher, 3000 to 5000 

feet, but more protected locations could see ceilings drop to 

around 2000 to 3000 feet at times. Mountain waves have been 

observed across the area and may affect air travel. Visibility 

could be as low as 1 mile early this afternoon in heavier snow. 

Ceilings, precipitation, and visibility are expected to improve as

that front moves southwestward after midnight into Friday 

morning. The timing could be delayed though, which would lead to 

conditions persisting a bit longer. Winds at may not see 

substantial improvements until almost Saturday.
