Following this first front moving through the panhandle tonight, there is going to be an atmospheric river pushing into the southern panhandle by tomorrow afternoon that will result in moderate to heavy precipitation. This moderate strength atmospheric river is expected to have IVT values of over 500 kg/ms and will have its strongest impacts in the southeast panhandle around Ketchikan and Annette Island. This is expected to bring rainfall totals between 2.5 and 3.5 inches to the southern panhandle between Tuesday afternoon and Wednesday afternoon. The rest of the central and northern panhandle will still see some moderate to heavy

ESFAFG A moderate to heavy run of ice on the Porcupine River will be passing Fort Yukon today. The heavy run of ice from Old Crow breaking up on Saturday morning was about 100 miles upstream from Fort Yukon as of 1pm Sunday. Water and ice levels with this run of ice are covering sand bars, but no significant water or ice has been seen overbank. Light runs of ice will continue through the week. The Porcupine River at Old Crow broke up Friday night and jammed just downstream from Old Crow causing moderate flooding before releasing Saturday morning. The

A gale force low is expected to swing through the eastern Gulf of Alaska early next week, bringing elevated seas to the eastern Gulf. If the current projected timing and strength of this low remains, it would line up with high tide, which would result in higher than normal water levels Monday night into Tuesday of up to 1 foot above normally expected forecast high tide. . Boats that are docked on the western side of of Prince of Wales Island and near Port Alexander could be impacted by the higher than normal water levels. Stay tuned into the forecast

ESFAFG The Porcupine River at Old Crow broke up Friday night and jammed just downstream from Old Crow causing moderate flooding before releasing Saturday morning. As of noon Saturday the Porcupine River had broken up past the US border. The Porcupine River at Fort Yukon is currently ice free, but light to moderate runs of ice can be expected to begin today through the middle of the week with water levels on the Porcupine River rising through the week into next weekend. At this time no flooding is expected as these runs of ice move past Fort Yukon.
Special Weather Statement issued May 25 at 9:56AM AKDT by NWS Fairbanks AK
Increasing moisture and instability over the Eastern Interior will bring heavy rain showers and widely scattered thunderstorms through Monday. The atmosphere over the holiday weekend will be more typical of late July than the end of May. Storms that do form today will not move quickly and may be nearly stationary, which will allow them to drop abundant rainfall over small areas. Not all areas will see rainfall, but creeks and streams near areas that do see heavy rain may rise rapidly, especially in steep terrain. By Monday, the bigger threat from these thunderstorms will be strong outflow winds, abundant

More thunderstorms are expected today, but they will be potentially stronger and more widespread than Sunday, with additional instability. This means storms may produce locally heavy downpours with frequent lightning and small hail. Winds aloft will be from the east- northeast, so storms will likely form over the higher elevations of the White Mtns, Yukon-Tanana Uplands, and the Upper Chena Basin then drift southwest into lower elevation valleys. As they fall apart, also expect the potential for brief strong and gusty, erratic winds. In addition, locally heavy rain amounts are possible over the Western and Central AK Range with a
