Good Morning, Las Vegas: Extreme Heat continues, tracking mosquitoes in the valley

KTNV — That Extreme Heat Warning continues today, and we might even set some weather records today, so it's important to stay safe and cool today.

Plus, officials are tracking mosquito activity throughout the valley as they have been reported in multiple zip codes.

Extreme Heat Warning and Heat Advisory in effect until Saturday night. High pressure centered over the four corners will continue to bring us dangerously hot and humid conditions across Southern Nevada through Saturday.

Monsoon moisture will continue to move into the region giving us a chance of scattered showers and storms starting on Friday and that will continue through early next week.

Following up: North Las Vegas again denies charter school applications

The City of North Las Vegas is looking to provide more educational options for families by exercising a new law that allows municipalities to authorize and oversee their own public charter schools.

But it looks like none of the applications meet what they're looking for.

The council first denied them earlier this summer over financial concerns, among other things. Applicants can revise and resubmit.

We have a crash causing some congestion on the 215 westbound right around Green Valley Parkway.

Drivers hoping on the 215 from Pecos and St. Rose will be greeted with police activity. This is in an area already seeing some lane reductions due to construction.

The good news is that the roadways in the rest of the valley look mostly clear.
