LONG DURATION HEAVY RAIN AND RISING FREEZING LEVELS THROUGH MONDAY... A warm front will cause precipitation to track into the region from south to north on Friday. A wind shift out of the south with increased speeds will allow warming temperatures through the northern inner channels Friday evening. Meanwhile, snow/freezing levels will steadily rise. Freezing levels over Juneau will rise to around 3,000 feet Friday night, then on Sunday, these values top out at over 4,000 feet. Rainfall totals over this 4 day period will vary as two or more surges of moisture move through, but are likely to reach 1-2 inches each day. Greatest rainfall rates currently expected on Friday night and Sunday, and Monday. Rain on significant snowpack currently in place can result in several impacts: * Snow will become heavier as it absorbs the rain, making it more difficult to move. * Heavier snow may affect susceptible properties and vessels. * Drainage blocked by snow will cause rainfall runoff and snowmelt onto streets and ponding. * Rain on hard-pack snow will become icy. * Snowmelt from high elevation snow will add to runoff. The City and Borough of Juneau asks residents to provide assistance with clearing drains on or near their property to reduce the risk of flooding. Residents are also asked to please keep fire hydrants clear and shovel snow off their vessels in the harbors. Local avalanche forecasters with CBJ, DOT, and AEL&P are expecting an increased risk of avalanches in known avalanche paths through this event. Please refer to those entities for more information on the risk of avalanches or visit juneau.org/avalanche. Stay tuned to updates from the National Weather Service on this developing pattern change.
