HRRR Radar Model

This radar simulation runs from 9:00 a.m. to 11:00 p.m. this evening. Note the scattered nature of today’s storms, but don’t focus on specific locations of storms on this simulation. It’s good, but it’s not that good. ha

On This Day 

1886 – The town of Indianola, Texas, was completely destroyed by a hurricane, and never rebuilt.

1910 – The big blow up of forest fires finally came to an end in Idaho. A record dry August fueled 1,736 fires which burned three million acres destroying six billion board feet of timber. The fires claimed the lives of 85 persons, 78 of which were fire fighters, and consumed the entire town of Wallace. The smoke spread a third of the way around the world producing some dark days in the U.S. and Canada. The forest fires prompted federal fire protection laws.

Hurricane Forecast

An area of low pressure may become “Danielle” before making landfall somewhere near the Mexico/Texas this evening. These same areas were hit by another tropical system about a week ago. That system dropped 5-10 inches of rain on that area.

Yet another tropical wave will be monitored over the coming week as it moves off the coast of Africa.

Other important information will be shared when needed. This includes additional severe weather information, model data, drought info, hurricane info, and more. Many of these can be found as tabs to this page at any time.
