WeatherWatcher: Wind Advisory issued, last 2 weeks of data

Sunday, February 24, 2013

  • Wind Advisory issued Sunday night - Monday morning
  • The week ahead
  • Friday almost storm
  • Last two weeks of data
Wind Advisory: The National Weather Service in Seattle has issued a Wind Advisory for Western Washington, including Shoreline and Lake Forest Park. The advisory is in effect from 11pm Sunday night until 4pm Monday. This is a widespread wind event expected to cover the entire region. Winds are expected to increase late this evening to 30mph with gusts to 55mph. This will be a bit stronger than the Friday weather we had. Winds this strong can snap tree limbs and bring down small or shallow rooted trees. Local power outages are very possible. Unlike Friday, I am expecting this to be one of the most significant storms we've have had so far this season.

The Week Ahead: Monday through Friday we are going to be in a more normal wet weather pattern compared to the past two months. We have a series of storms marching from the Pacific Ocean into the Northwest that will keep us under grey skies and rainy days for the days to come. This pattern will likely last us through next weekend. Wind storms may be another factor through out this week as the current weather pattern favors the development of wind events. Keep checking back for any news on new storm advisories or warnings.

Friday's almost a storm: The weather system that moved through on Friday was making headlines on the news with warning of the first significant storm to move into the area in a while. This storm did not meet any advisory or warning criteria from the National Weather Service. I will give it some credit that it was indeed a breezy to windy storm. There were some small tree limbs on the streets after this storm but it didn't appear to be anything serious, as I had expected. Friday, however, does signal a change in our weather pattern. The pesky high pressure bubble that has been dominating our region for most of the last 8 months (with the exception of our stormy weather in November and December) has receded once again to allow weather systems to move through our area to bring us a return to our regularly scheduled winter. Even though the El Nino Southern Oscillation index has been rated as neutral all winter, we've been having patterns more like a strong El Nino so far this winter with the exception of November and December. There are signs that this may be the last of that high pressure bubble until May or June.  I'll have more information on this as the current weather patterns develop.
