It's summer, and that means warm weather and lots of sunshine. But it's not all beaches and barbecues: The summer weather can, literally, be a killer. Our first slide is a tragic case in point. The Yarnell Hill fire in Arizona started on June 28, and it killed 19 of the state's top firefighters just two days later.

Thunderstorms across the Washington, D.C. area on June 13 wreaked havoc on roadways like this stretch in Olney, Md.

A massive storm system moved through Illinois on June 12, with lightning striking the Willis Tower downtown Chicago.

An June 9 tornado popped up in Nice, France. The area sees a twister about once per year.

The West Fork Complex fire in Southwestern Colorado burned out of control late in June.

Fires raged across Indonesia's giant rainforests, causing Southeast Asia's worst air pollution crisis in years. Here smoke emanates from the grounds of a private palm oil concession company on June 29.

Colorado has had a difficult start to summer. Here, the Black Forest Fire burns northeast of Colorado Springs on June 12, engulfing a barn with ease.

Fire hasn't been the only problem in Colorado. A flood of mud and debris was unleashed in Manitou Springs on July 1 after sudden rains hit scars from last year's Waldo Canyon fire.

Torrential rains that swept across Southwestern China drove rescuers out into flood-ravaged areas on July 1 to help evacuate residents.

India has had its share of terrible problems with flash flooding and landslides. The torrents have killed more than 1,000 people in northern India. Here damaged houses dangle precariously above the flash-flood eroded Mandakini river on June 26.

A May 20 tornado destroyed the town of Moore, Okla., killing more than 20 people and demolishing homes and businesses. The two-mile-wide twister was an EF5 level storm, the strongest measure meteorologists have for tornadoes.

El Reno, Okla. was caught in a May 31 twister that killed 18 people, including six children. The tornado was also an EF5, and, at 2.6 miles wide, it was the widest ever recorded.
