FNAK71 PAFC 181658 FWSAER Spot Forecast for Little Granite Creek RX...SOA DFFP National Weather Service Anchorage AK 858 AM AKDT Mon May 18 2026 Forecast is based on ignition time of 0900 AKDT on May 18. .DISCUSSION... The overall pattern will not change much over the next few days with a low in the Bering Sea sending multiple upper level waves through the area. Specifically for the Little Granite Creek burn area, this will likely bring west or west-northwest winds to the site again this afternoon and evening similar to the past two afternoons. One of the upper level waves will move are the burn site early Tuesday morning. However, it looks likely that the Chugach Mountains will block the rain with only sprinkles making it to the burn site. Winds Tuesday have a little more uncertainty to them as the upper level wave will move through on Tuesday. The most likely scenario will be for east to northeast winds late tonight into Tuesday morning that shift to the southwest to west late Tuesday morning through afternoon. .TODAY...
