Already this month, a series of storms moving through southern Alaska has buffeted Anchorage with a lot of rain and wind. There was a huge wind storm earlier in the month that brought down power lines as winds gusted well past 100 mph in spots. Another big storm hit over the weekend bringing over an inch of rain and a round of strong winds, and today another storm is pounding the area. Here is a midday satellite picture of the area.
Today's storm as of midday had already brought over 1.40 inches of rain to Seward and over an inch to Kneai. As you can see by the satellite picture, moisture is being brought north from much lower latitudes right up into south-central Alaska. The current rainy weather will diminish some tonight and winds diminish, but the next storm is not that far away. The same satellite picture shows it nicely over the western Aleutians and the surface map shows a well-developed 996 mb low.
This storm is likely to spread more rain, some heavy, back into the area tomorrow into early tomorrow night. I don't think this will be quite as windy of a storm, but more downpours could cause some local flooding problems.
Are we done then? No! Yet another pretty good storm looks on track for Friday night into Saturday, and this one too may be accompanied by locally strong and damaging winds and pretty hefty rain amounts. Yet another storm is forecast to arrive next Tuesday.
So far this month, 2.79 inches of rain has fallen in Anchorage as of midnight last night. That was well above the normal of 1.81 inches. The normal amount of rain for the entire month is 2.99 inches, and that will be easily surpassed before we get much past the weekend.
Many think of Alaska as the Great White North. Though very true for quite a few months, right now this part of Alaska can be thought of as the Great Muddy North.
These is the possibility that another surge of tropical moisture could move into Arizona and Southern California by the middle of next week.
I still believe the greatest amount of rain, at least partially relating to Norbert, occurs from southeast California to Arizona
The effects on Southern California are very much in question.
With low wind shear and warm water in its path for a while longer, it is likely that Norbert intensifies into at least a Category 2 storm.
For much of the last week the monsoon moisture flow into the Southwest has been completely shut down by dry westerly winds. This is about to change.
A big pattern change is underway, one that will completely shut down any chance of showers and thunderstorms for an extended time period.
