Trick-or-Treat Forecast

Much of the country will have quiet weather for Halloween on Wednesday with the exception being Florida and coastal areas of Georgia and South Carolina as Tropical Storm Noel approaches. Windy and rainy conditions will engulf much of Florida, especially the eastern half, throughout the day on Wednesday and continuing into the overnight hours. Weather conditions will improve across the region on Thursday as Noel turns to the northeast away from the Southeast coastline. Elsewhere, a storm system moving across Canada will drag a front through the Midwest bringing showers ahead of and a rain/snow mix behind the front. Windy conditions will prevail behind the front Wednesday night across the Upper Midwest. A weak front will move into the Pacific Northwest on Wednesday with scattered showers lingering into the early evening hours.

Temperatures will be chilly across much of the northern US from the Pacific Northwest eastward into the Midwest. Meanwhile, more pleasant weather will be in store across the South with dry and mild conditions expected.

California wildfires on HW SuperSats

Santa Ana WindsWildfires have been raging out of control across Southern California for the past several days, fueled by dry ground conditions, low humidity and very strong Santa Ana (offshore) winds. Large wildfires are reported across seven counties in the region surrounding San Diego and Los Angeles where almost 250,000 acres have burned and thousands forced to evacuate from their homes and communities. Winds have peaked well over hurricane force and in several cases have reached as high as 100 mph. High wind and fire advisories remain in place for the region as conditions will remain quite favorable for continuing and additional wildfires.

Our SuperSat imagery (via HAMsat) clearly depicts the smoke rising from the fires on the ground as well as the strong Santa Ana winds carrying the smoke plumes westward over the eastern Pacific. The following image was from around 4:30 PM EDT (1:30 PM PDT) which shows the major fires burning at the time. The clockwise flow around the strong area of high pressure which is helping to create the strong offshore winds can also be seen as the smoke begins to flow more towards the northwest once over the Pacific Ocean.

Tropical Wind Field Forecast Images

Thank you Kiko! 

Thanks to Tropical Storm Kiko, I was finally able to debug the wind field forecast plotting in the HWTropical 3 plugin.  HWTropical 3 uses data obtained from the forecast advisory product to generate the maps. The feature includes the ability to display the wind fields for each individual location or to have a forecast swath plotted. That data supports plotting forecasted wind fields at 34, 50 and 64 knot intervals.  I will be cleaning the code and adding support to the templates for including in HWTropical 3.0 Final.  Look for a release over the next day or two.

So, where’s the HWearthquake plug-in?

I have made several posts in the support forums regarding the upcoming release of the HWearthquake plug-in, suggesting that it is finally nearing its initial public release. The most recent announcement stated it was being wrapped up and would be released that week. However, after discussing the plug-in with Lee, we decided to perform a release for HWearthquake similar to that we did for HWtropical 2.0, and the HW site will receive a completely new content area that will greatly expand upon the HWearthquake plug-in. Thus the plug-in’s initial release will occur around the launch of our new content area whose date still has yet to be determined. We will continue providing periodic updates regarding the release status the plug-in.
