Critical fire weather returned to the Western U.S. on Monday as the central part of the country faces some scorching heat.

The increased chances for wildfires are expected in Western states throughout the week.

A combination of hot temperatures, low humidity, dry lightning and gusty winds will bring an elevated risk of critical fire weather across the Inter-Mountain West, Southwest and Southern Rockies.

The thick layer of Saharan dust we’ve been watching for the past 10 days or so continues streaming across the Atlantic, Caribbean, Gulf of Mexico, and into the southeastern U.S.

While the majority of this dust travels above the surface, creating colorful sunsets and hazy skies, some dust at ground level can aggravate those with sensitive respiratory systems.

Dust in the atmosphere prevents hurricane development, and as such we aren’t forecasting any activity across the Atlantic for at least the next week.
