The National Weather Service issued a flood advisory in effect until noon Monday due to heavy rainfall in the Juneau area.

According to the weather service, between 1.5 and 3 inches of rain had fallen in the last 18 hours as of 1 p.m. Sunday. Up to 5 inches were expected to fall by noon Monday.

Juneau lead forecaster Pete Boyd said we’re returning to typical weather for this time of year after an unusually warm and dry September.

“This is definitely getting into normal for fall. However, the rainfall rates, especially at this time, are rather high,” Boyd said.

Boyd said the advisory means they are monitoring water levels in Mendenhall Lake and Montana Creek, as well as other local streams.

Water levels in Montana Creek are expected to crest around 4 a.m. Monday. That could lead to several inches of water on the low parts of Montana Creek Road.

Boyd said Sunday the weather service had not received any reports of flooding. The Alaska Department of Transportation reported mudslides covering a portion of the Haines Highway Sunday morning.

The weather service warns that mudslides are possible in areas with steep terrain.

As for an end to all the rain, Boyd said any respite will be brief.

“As we get into kind of Monday night into Tuesday, there’s a bit of a break, possibly, before the next system moves in, and then after that we are just system after system,” Boyd said. “So we’re back to our typical fall, ‘Hey it’s dry for half a day’ and then we have more rain moving in.”

The forecast shows nothing but rain for at least the next week.
