23 Aug 2012, Glen Canyon National Recreation Area, USA, USA, USA --- Towering storm clouds block my exit as I leave a remote area of Lake Powell in the middle of monsoon season. The problem with the dirt roads in the area is that they turn into an impassable goo when wet. It doesn't matter if you have all-wheel drive, 4-wheel drive or a sherman tank - you will get stuck. I made it out about 2 hours before the roads were washed out. --- Image by © Doug Meek/Corbis
19 Jun 2011, Nebraska, USA --- An amazing supercell tracks across southern Nebraska, producing other-worldy storm structures. At times this storm looked like a giant tsunami in the sky. The supercell formed after two supercells merged near McCook Nebraska. It then tracked eastward as one storm till it died after midnight east of Hastings Nebraska. --- Image by © Mike Hollingshead/Corbis

As the rainy season in Kenya begins, late afternoon clouds build as a prelude to rains that will revitalize plant and animal alike.
