Tropical moisture continues to impact Southcentral
Moisture that has its origins in Hawaii continues to fall across Southcentral. At the time of this post, many areas have seen over half an inch of rain, with the highest totals occurring along coastal regions. Homer has already seen over .75 inches, with Anchorage just shy of half an inch of rain. As the low continues to push off to the east very slowly, we'll see rain become more showery in nature through the night. Even with that said, many areas can still expect to pick up an additional .10 to .20 inches of rain by Monday morning.
Due to the overcast skies and light rain that will continue to fall, temperatures overnight will only dip into the mid 40s. Although that may be the case, snow will still occur in the higher elevations of the Chugach, with the heaviest snow occurring across the Central Chugach. A few AM showers will linger for Monday before we see the activity taper off. The main focus for rain will be across the Prince William Sound tomorrow and Southeast by tomorrow evening. While this means that a good portion of Southcentral will be on the backside of the storm system, it won't last long.
The storm is expected to retrograde Monday night into Tuesday, bringing another round of rain to Anchorage and the Mat-Su. Many areas will see an additional .30 inches of rain, with afternoon highs topping out in the 50s. As the storm retrogrades, expect winds to pick up out of the north through the day gusting as high as 30 mph.
September will end on a wet note and while it won't be the wettest on record, it certainly is a welcoming change from the dry summer.
Have a great start to your work week!
