Heavy rain from Southeast to Southcentral
While it's not drought-busting, some much needed rain has been falling across areas hit hardest by drought conditions. An atmospheric river, an area of strong winds that transports moisture from the tropics, has set up shop over Southeast Alaska bringing very heavy rain and windy conditions. Many areas have already seen in excess of 3 inches of rain through the course of today, with more expected into the weekend. While the heaviest rains has been situated across Southeast, a decent amount of rain has also fallen across Southcentral. Several spots in the Anchorage Bowl are seeing upwards of half an inch of rain, with higher amounts along Hillside and higher elevations.
While the rain has certainly been beneficial to the area, the extent at which it's falling and how much is surprising. With Anchorage already exceeding half an inch of rain for today, it's the third time this month we've done so and only fifth out of the entire year. The single most greatest was on May 26 when three quarters of an inch of rain fell. Following that, high pressure build into the Gulf of Alaska, ultimately shaping our record hot and dry summer. The heaviest rain has tapered off across Southcentral, but expect light rain to continue through the night into early Saturday morning.
Because of the continued rain, a flood advisory is in effect for the Anchorage Bowl until 5:45 Saturday morning. Following that we should dry out with a nice stretch of weather returning to the area. While the upcoming forecast doesn't bring the wet pattern we've been seeing in Southcentral, we will see cooler weather and temperatures dipping into the 30s overnight for the first time since May 22.
Enjoy the weekend!
