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 continues to be possible.

* WHERE...The following area, Northern Inner Channels. This includes the cities of Skagway, White Pass, And Haines.

* WHEN...From late tonight 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.

Affected area: Municipality of Skagway; Haines Borough and Klukwan
