Heavy rain started falling across Anchorage Tuesday evening, not letting up until late Wednesday. Ted Stevens International Airport recorded 0.88 inches of rain in that time, with 0.69 inches falling between midnight and 10 p.m. Wednesday. This is the most rain ever recorded in Anchorage on September 18th, completely smashing the previous record of 0.49 inches set in 1992. 

The heavy rain meant a lot of standing water on city roads and more water being funneled into area creeks and streams. The National Weather Service issued a Urban and Small Stream Flood Advisory for Anchorage late Wednesday morning for the high water.

Campbell creek climbed from 2.38 feet to 4.75 feet throughout the afternoon and evening. Action stage for the creek begins when the water reaches 3.7 feet. Minor flooding begins occurring at 4.3 feet and by 5 feet moderate flooding is expected. A flood advisory for flooding along Campbell Creek is in effect until 7:30 a.m. Thursday, at which point most of the rain will have ended and the creek will likely begin to drop.

The storm that brought the rain to the area is now moving east. Most of Southcentral will see drier weather Thursday with sun breaks and highs in the upper 50s. Enjoy the drier weather while it lasts though because the next storm arrives late Thursday night. 

Another half of an inch of rain is likely Friday and Saturday as scattered showers continue for Anchorage. It's back to dry conditions late Saturday, although cooler air will move in behind these storms and temperatures will fall to the lowest levels we've seen this season. Expect temperatures in the upper 30s and low 40s Sunday morning with high temperatures struggling to even reach the low 50s Sunday afternoon. 

The freezing level will also begin to drop this weekend, meaning termination dust is looking likely for the Chugach mountains.

Enjoy the sun breaks between the rain showers this week and get ready for the fall-like temperatures to move in!
