Flood Watch issued September 18 at 2:52PM AKDT until September 21 at 4:00AM AKDT by NWS Juneau AK

2:52 PM — September 19th, 3:00 AM

A series of low pressures will move through the panhandle this weekend bringing prolonged rain combined with high freezing levels to increase ice melt on glacier river systems. The heavy rainfall and associated runoff will produce significant river rises with the potential of minor flooding. * WHAT...Flooding caused by excessive rainfall is possible. * WHERE...Including the following area, Northern Inner Channels. This includes the cities of Skagway, White Pass, And Haines. * WHEN...From late Saturday night through late Sunday night. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, other low-lying areas and flood-prone locations. * ADDITIONAL DETAILS... - A series of lows will bring a prolonged period of rain combined with warmer temperatures aloft allowing for any precipitation falling into the region to remain as rain. Current thinking is that the rain will continue this evening into Saturday before a second, stronger system moves in for Saturday into Sunday. Between the two systems, the flow is expected to remain onshore keeping moisture moving into the area. For the Skagway area, 24 hour precip looks to get up to 1 to 2 inches this weekend while the storm total amounts could be 2 to 4 inches. The Haines area is expected to see 0.75 to 1.5 inches in 24 hours while a storm total precipitation of 2 to 3.5 inches is possible.

Special Weather Statement issued September 18 at 3:04PM AKDT by NWS Juneau AK

3:04 PM — 11:15 PM

Heavy rain and strong winds are expected to continue through this evening and last through the weekend as multiple strong low pressure systems move into the northern gulf. These lows will bring multiple days of moderate to heavy rain, with around 1.5 to 3 inches of rain every 24 hours. Some areas, especially near Yakutat and along the gulf coast, could see localized areas reach around 4 inches of rain in 24 hours. Heaviest rain rates are anticipated late Saturday into Sunday with hourly rates of 0.15 to 0.3 inches possible. This heavy rain will likely cause rapid river rises along smaller rivers and streams, but no flooding is expected at this time for areas outside the flood watch. Along with this heavy rain, increased winds are highly likely across the area. Strongest winds are anticipated to occur late Saturday into Sunday with 30 to 40 kts, gusts to 50 kts across the gulf and 20 to 35 kts, gusts around 40 to 50 kts across the northern inner channels. Land winds will also increase, with areas especially along the central gulf coast seeing wind gusts up to around 45 mph. Check back for more updates through the weekend.
