CARSON CITY, NEV. ? Nevada continued to endure lightning-sparked wildfires on Wednesday, but an approaching rainstorm – complete with a flood watch – held the potential to douse some of the flames.

In all, about 140,000 acres of the state have been charred since the fires began over the weekend. Of 33 large fires burning in the U.S. and being tracked by the National Interagency Fire Center, 10 were in Nevada.

But three consecutive days of high temperatures, low humidity and dry lightning were forecast to give way Wednesday night to a possibility of heavy rain. A flash flood watch was posted for the hard-hit Reno-Carson City area.
