Flood Watch issued September 16 at 2:03PM AKDT until September 19 at 4:00PM AKDT by NWS Fairbanks AK

Summary: * WHAT...Flooding caused by excessive rainfall is possible. * WHERE...Including the following areas, Fairbanks, North Pole, Two Rivers, Fort Wainwright, Ester, and Fox * WHEN...Through Saturday afternoon. * IMPACTS...Heavy rain may result in minor flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. * ADDITIONAL DETAILS... - The Chena River is running higher than normal and will continue to be high through the week. Showers will continue through the end of the week, with the bulk of the rainfall expected through Thursday morning. Storm total rainfall during this time will be around 0.50" to 1.00". It has been very wet lately and this amount of rain has the potential to bring the Chena and Little Chena Rivers above minor flood stage beginning Thursday afternoon into Friday. - This means low-lying and typical flood-prone areas may experience areas of flooding through the end of the week as water levels gradually rise then fall. In addition, while we are not expecting much flooding away from rivers, streams and creeks, as the ground is already saturated and may struggle to hold more water. This can lead to pooling and ponding of water across the area which may make travel difficult in localized spots. - There is some uncertainty with exact timing and amounts of rainfall but as details become clearer, we will continue to update. - For more updated river information, please refer to water.noaa.gov or weather.gov/aprfc

Flood Advisory issued September 16 at 11:35AM AKDT until September 17 at 1:00PM AKDT by NWS Anchorage AK

Summary: * WHAT...Flooding caused by onshore flow restricting Kuskokwim River drainage in combination with excessive rainfall continues. * WHERE...Lower Kuskokwim including Napakiak, Napaskiak, Oscarville, Bethel, and Kwethluk. * WHEN...Until 100 PM AKDT Thursday. * IMPACTS...Minor flooding in low-lying and poor drainage areas. River or stream flows are elevated. Ponding of water in areas is occurring or is imminent. * ADDITIONAL DETAILS... - At 1130 AM AKDT Wednesday, the river gauge at Bethel indicates water levels above flood stage, at or above 8.5 ft. Additionally, reports out of the Lower Kuskokwim, including Napakiak, Napaskiak, Oscarville, Bethel and Kwethluk, confirm flooding in low-lying areas. Water levels may drop with the outgoing tide this (Wednesday) afternoon, but are expected to rise again Thursday morning with another high tide cycle. These high water levels are a result of the Kuskokwim River back-up at its outlet in combination with heavy rain runoff farther upstream. Minor flooding will continue from overflow of poor drainage areas. High tides will decrease later in the week, allowing the backwater of the Kuskokwim River to drain, lowering water levels to below flood stage. - For Kuskokwim River at Bethel: At 11:30am Wednesday the reading was 8.9 feet. Flood Stage is 8.5 feet. Impacts: At 7.0 feet: Action and bankfull stage. At 8.5 feet: Minor flood stage. Water starts to back up along Brown Slough and flood low lying areas. - Http://www.weather.gov/safety/flood
