In this article we provide continuous updates for a variety of Weather and Weather Related Threats. One important group of threats are Mesoscale Events. A Mesoscale Event is smaller than a large scale or Synoptic Event like a major storm but larger than a micro-climate. Although they sometimes are forecast days in advance, they often spring up fairly quickly which is why we are publishing this report.
Special Attention This Week: The West Coast especially the Northwest with respect to Wind, Waves and Precipitation. There could actually be some wildfire hazards in places this week.
Please share this article – Go to very top of page, right hand side for social media buttons.
You will see a number of different maps which are updated in real time, this making this a “live” report. If a part of one or more of the maps shows an area that is highlighted, you can click on it and get the full current report. By having the reader click on these active situations rather than having GEI do so, you will not miss any events in which you might have an interest and which we had not noticed and the page will not get cluttered with warnings etc that have since expired.
Our focus here are events that are likely to last in the range of six hours but there can be longer or shorter events that are addressed by the Storm Prediction Center which is the main source of the information in this article.. Long-term major events like a Hurricane are more likely to be in a separate article. But that may not always be the case. Since in general, all the links on this page transfer you into the NOAA system, in order to get back into this article you need to either close the tab to which you were transferred or click back on the tab that has this article.
Overview: These Two Maps Provide Information but are NOT Set up to Provide More Detail. They should update daily but have not updated now for two days.
I have added this graphic:
Live Warning Maps which If Severe Weather is Shown can be Clicked on to Get More Detail about these events. I some cases we have been able to add a larger map to the standard map provided by SPC and other NOAA Agencies. Over time we expect to be able to find larger maps for all the warnings. But until then the smaller maps work fine as you are just looking to see if there is a current warning. If these is click on the map for additional information related to the event.

If there are green areas shown on this map, it means that there are currently or anticipated areas of severe weather events. Clicking on the U.S. map will take you to the MPD page at the NOAA where there is information on each of those mesoscale events. |
