RENO, Nev. (AP) — The National Weather Service has issued the first red-flag warning of the season in Nevada because of hazardous conditions expected to raise the threat of wildfires across nearly the entire state through Thursday night.

The service said Tuesday gusty winds and low humidity will increase the potential for wildfires from the California line to the Utah line for all but the extreme northeast and southeast corners of Nevada from 11 a.m. Wednesday through 11 p.m. Thursday.

The warning includes the Lake Tahoe region, parts of northeast California, all of the Sierra front and stretches as far south as Las Vegas where high temperatures are expected to hover around 100 degrees (38 Celsius) all week.

A wind lake advisory also is in effect for much of northern Nevada where winds are forecast to gust in excess of 35 mph (56 kph).
