...WIDESPREAD SNOWMELT AROUND SOUTHCENTRAL ALASKA RESULTING IN ELEVATED WATER LEVELS ON ALL AREA RIVERS... REASON FOR STATEMENT: WARM TEMPERATURES THIS WEEK HAVE CAUSED SOUTHCENTRAL RIVERS AND STREAMS TO BECOME SWOLLEN WITH SNOWMELT. A SIGNIFICANT SNOWPACK REMAINS IN THE UPPER ELEVATIONS DUE TO THE COOLER THAN NORMAL SPRING. WARM TEMPERATURES AND HIGH FREEZING LEVELS WILL PERSIST THROUGH SATURDAY BEFORE A PATTERN CHANGE ON SUNDAY BRINGS A RETURN OF COOLER ONSHORE FLOW. RIVER LEVELS WILL CONTINUE TO RISE AND LIKELY CREST THIS WEEKEND. ISOLATED THUNDERSTORMS THURSDAY MAY CAUSE FURTHER RISES. EXPECTED IMPACTS: AT THIS TIME...FLOODING IS NOT EXPECTED ALTHOUGH SOME RIVERS AND STREAMS MAY APPROACH BANKFULL OR EXPERIENCE VERY MINOR LOCAL FLOODING IN LOW LYING AREAS. WATER LEVELS WILL BE HIGH ENOUGH TO CAUSE LOCAL BANK EROSION ESPECIALLY ALONG THE MATANUSKA RIVER. RECREATIONAL ENTHUSIASTS SHOULD EXERT CAUTION AND BE ALERT FOR HIGH WATER. WHETHER YOU ARE DRIVING OR WALKING...IF YOU COME TO A FLOODED ROAD...TURN AROUND DON`T DROWN.
