Fire risk out to the west for Monday

Focused in the Great Basin and the Four Corners

While recent rains have kept us in good shape, we’ll hold onto a dry and warm Monday as both a new work week and the month of June kick off. With an upper-level ridge in the central United States and an upper low becoming cut off west of the Baja Peninsula, however, those systems will come into play with a developing surface pressure trough over the lower Colorado River Valley and the Great Basin. These systems will contribute to an impressive mid-level flow expected to range between 45 and 55 mph. At the surface, a south-southwest wind at 20-25 mph and a low relative humidity between 8% and 15% will contribute to a critical fire risk across western Utah and eastern Nevada. The elevated fire risk surrounding that and covering other parts of Nevada, Utah, Arizona and Colorado will still have a fire risk with a lighter wind being the limiting factor. The risk will be the highest during Monday afternoon and early Monday evening before a rise in humidity and a slight drop in wind speeds will lessen the fire risk for Monday night.
