More than 120 people died of heatstroke in the Tokyo metropolitan area in July, when the nation's average temperature hit record highs and heat warnings were in effect much of the month, Japanese authorities said Tuesday.

According to the Tokyo Medical Examiner's Office, many of the 123 people who died were elderly. All but two were found dead indoors, and most were not using air conditioners despite having them installed.

The center of Hurricane Debby is expected to reach the Big Bend coast of Florida early Monday bringing potential record-setting rains, catastrophic flooding and life-threatening storm surge as it moves slowly across the northern part of the state before stalling over the coastal regions of Georgia and South Carolina.

Fire crews battling California's largest wildfire this year have corralled a third of the blaze aided in part by cooler weather, but a return of triple-digit temperatures could allow it to grow, fire officials said Sunday.

Cooler temperatures and increased humidity gave firefighters "a great opportunity to make some good advances" on the fire in the Sierra Nevada foothills, said Chris Vestal, a spokesman for the California Department of Forestry and Fire Protection.
