High winds blew across the Deltana and Tanana Flats region as a warm front pushed through from the south. Strong pressure differences between this frontal boundary and high pressure to the south of the Alaska Range created wind gusts measured up to 73 mph at the Delta Junction ASOS site.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

NORTH ALASKA FORECAST DISCUSSION
420 AM AST TUE FEB 4 2003
...UPDATE...WE JUST DECIDED TO HAVE THE FREEZING RAIN START IN ZONES
212...210 E PABL...AND 217 THIS AFTERNOON. OTHERWISE NO CHANGE.
THE OCCLUDED FRONT THAT WAS MOVING NORTH OVER BRISTOL BAY AT THIS
TIME MON IS NOW DIFFUSE NORTHWARD FROM A LITTLE REMNANT LOW NEAR
PAUN TO PASK THEN NORTHEAST AND EAST OVER ZONE 218. IT IS STILL
MAKING SOME SNOW OVER NORTHWEST ALASKA BUT WILL DISSIPATE BY NOON...
ONLY BECAUSE WE HAVE ANOTHER FRONTAL SYSTEM INCOMING. THE TRIPLE
POINT ASSOCIATED WITH THE ORIGINAL SYSTEM IS SOUTHEAST OF CYEV...WITH
THE WARM FRONT SOUTHEASTWARD FROM THERE. THE COLD FRONT BECAME A
TRAILING FRONT FROM ABOUT CYEV TO PAMD AND SOUTHWEST MON EVENING. IT
HAS NOW BEEN REACTIVATED...COMING BACK NORTHWEST AS A WARM FRONT
ASSOCIATED WITH THE 974 MB LOW 350 MILES SOUTH OF PASD. THIS WARM
FRONT IS MOVING RAPIDLY...AND WILL REACH A PAEH-PAGA-PABT BY 3PM TODAY.
(IT WILL BE DIFFUSE EAST OF PABT). IT WILL SLOW THEREAFTER IN THE
LIGHTER FLOW ALOFT BUT WILL REACH A PASM-PAKK-PAKP LINE BY 3AM WED.
THIS NEXT ONE WILL BE A BIGGER DEAL OVER OUR WEST COAST ZONES THAN
THE CURRENT REMNANT EVER WAS. WE REFERRED ABOVE TO THE LIGHTER FLOW
ALOFT OVER THE WEST COAST. THIS IS OF COURSE TRUE...AND WILL REMAIN
MUCH LIGHTER THAN THE HOWLING WINDS ALOFT OVER THE INTERIOR. HOWEVER...
WINDS ALOFT OVER THE WEST COAST WILL BE INCREASING TOO...ALLOWING THE
INCOMING FRONT TO HOLD TOGETHER BETTER...MAKING SOME SERIOUS SNOW
FARTHER WEST.
FREEZING RAIN IS LIKELY TO BE A SERIOUS PROBLEM IN ZONES 215 AND 216
TODAY...AND PROBABLY IN ZONES 212...210...AND 217 BEFORE EVENING AS
WELL.
BLIZZARD CONDITIONS MAY ABATE IN ZONES 207 AND 213 THIS MORNING...BUT
THINGS WILL DETERIORATE AGAIN THIS AFTERNOON.
