Shown above is a towering cumulonimbus cloud over western Guatemala, taken not long after sunset on January 15, 2017. I captured this attention-getting thunderhead from Sierra de los Cuchumatanes, about 9,850 ft (nearly 3,000 m) above the sea level -- the camera is facing south-southwest. I'm estimating the storm was approximately 50 (80 km) away, close to the summit of Volcán Santa María. It's massive top is spreading out along the tropopause, the boundary between the troposphere and the stratosphere, resulting in the mushroom-like shape. The lights of Malacatancito are in the mid-ground.
