Hydrologic Outlook issued January 8 at 8:40AM AKST by NWS Anchorage AK
ESFAFC Recent and continuing warm weather and widespread rainfall have led to rising creek and stream levels from the Kenai Peninsula north into the Mat-Su Valleys. Overflow has been reported on creeks and over existing trails. Increased streamflows may also lead to localized ice jams. Those traveling on backcountry trails are encouraged to take extra caution around area streams, rivers and trails, as water may degrade ice and create difficult or hazardous conditions. Additional warm and wet weather is expected this weekend, which may lead to additional river rises and overflow conditions.

ESFAJK There is increasing confidence in the mid and long range model solutions that a pair of atmospheric rivers will track into eastern half of the Gulf of Alaska and panhandle. The first feature will spread in its moisture band ( 1 to 3 inches ) and warming into the area Monday to Tuesday. Snow levels warming to around 3000 ft or higher. Rainfall event totals through around Wednesday/Thursday are 4-6 inches while NE Gulf coast may be closer to 8 inches of potential. Rain on top of new snow creating melt and run off will be the forecast challenge

ESFSEW Multiple weather systems will move across western Washington Friday through the weekend, bringing heavy precipitation at times to the Olympic Peninsula. Heaviest amounts are forecast over the southwestern slopes of the Olympic Mountains, with 2 to 4 inches of rainfall expected during this period. This will result in the potential for the Skokomish River to rise above flood stage over the weekend. Snow levels will initially be between 5000 to 6000 feet on Friday, and will drop between 3500 to 4500 feet Saturday and Sunday. Please monitor the latest river forecasts from the National Weather Service for additional information.

ESFBIS Colder temperatures will continue over the region through the weekend, with cold weather remaining in the forecast for the foreseeable future. This will once again cause ice to form on the Missouri River. While the river came close to icing-in just before Christmas, a return to warmer weather reversed that trend and removed some ice from the Bismarck and Mandan area. This time around, there is much less room in the river to store ice below the University of Mary, so the icing-in will likely occur very quickly once it starts. While it is impossible to predict exactly when

ESFSEW Additional frontal systems will bring precipitation to Western Washington at times through the weekend. While precipitation will be much less with the systems today and into this weekend, the lack of much of a break will keep rivers over the Southwest Interior rising into the weekend. The Chehalis River appears to be cresting this afternoon well below flood stage through Thurston and Lewis Counties, but will continue to monitor the Chehalis at Porter in Grays Harbor County as it is still forecast just shy of flood stage this weekend. Please monitor the latest river forecasts from the National Weather
