...FLOOD WATCH REMAINS IN EFFECT UNTIL 9 PM AKST THIS EVENING... An atmospheric river with multiple surges of moisture has moved into the panhandle and is possible to last into Sunday evening. Currently, convective rain showers are moving into the panhandle bringing localized moderate to heavy rain with breaks in between. Additional rainfall amounts from Friday night through Saturday night with ranges of around 0.75 to 1.5 inches before the next surge of moisture late night. Due to the localized nature of these showers, some areas may receive more rain accumulations than expected. For the northern inner channels, still expecting the deep sea level snowpack to absorb most rainfall from these incoming showers and produce minimal runoff. Therefore, the main hazard of concern is snow, ice, or other debris potentially blocking storm drains and allowing for ponding of rain and snowmelt in areas that they normally would not collect, such as roadways or walkways. Another surge of moisture is expected for the southern half of the panhandle overnight Saturday and continuing through Sunday. Very strong rain rates during the morning hours for the Ketchikan, Metlakatla, and Prince of Wales Island, with around a 40-60% chance for 3 hour rates exceeding 0.4 inches. This surge in precipitation may coincide with another surge of wind gusts, with sea level gusts possibly reaching as high as 50 mph. The southern panhandle could see 1.5 to 3.0 additional inches, the central inner channels could receive 1.0 to 2.0 additional inches, the Icy Strait corridor could receive 0.75 to 1.5 additional inches, and the Juneau area could receive 1.5 to 2.5 additional inches. * WHAT...Flooding caused by rain and snowmelt continues to be possible. * WHERE...The following areas, Northern Inner Channels near sea level. This includes the cities of Skagway, and Haines. * WHEN...Until 9 PM AKST this evening. * IMPACTS...Storm drains and ditches are clogged with snow that may cause ponding of water in these poor drainage areas. * ADDITIONAL DETAILS... - .Heavy rain falling on the existing snowpack, including recently fallen snow, leading to increased runoff and cause ponding in poor drainage areas. For areas previously cleared of snow, such as walk ways or roadways, the runoff is expected to be enhanced, as the older snowpack will likely absorb much of the falling rain through Saturday. Around one inch has fallen in the Haines area and around a half inch has fallen in the Skagway. On Saturday, with rain showers moving into the area, an additional 0.75 to 1.5 inches of rain is possible.
You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. Stay tuned to further developments by listening to your local radio, television, or NOAA Weather Radio for further information.
