Rain showers will pass over Anchorage this morning. Otherwise, expect drier conditions this afternoon. Winds will be the real challenge for the burn site today as strong and gusty winds through channeled terrain will make a chaotic wind situation. For this morning, the strong winds through the Chugach Mountains will shear off and produce an eddy effect over the burn area creating southwest to northwest winds that will generally remain under 10 mph sustained, but have some gusts up to 20 mph. After the front passes around noon, there is a good chance for the winds shift the southeast and increase to around 12 mph gusting 20 to 25 mph. This is not a sure thing, but looks like the most likely scenario at this time. Winds should diminish and turn northerly overnight and not be nearly as strong Wednesday. .TODAY...

Area will be impacted by weak systems moving along the backside of a ridge along the MT/ID border. Isolated showers/thunderstorms will be possible but amounts expected to be only a few hundredths of an inch. A stronger wave increases thunder and rain potential for Wednesday. Winds will be westerly with increased gusts in the afternoon.
