Description of the event

Tropical storm Otto left a trail of devastation over northern parts of Costa Rica as severe rainfall caused widespread flooding and landslides. The storm has claimed at least nine lives and displaced over 6000 people.

Otto made landfall in southern Nicaragua as a category two storm, with wind speeds of 110mph and moved south into northern Costa Rica where a month's worth of rain fell in a few hours. Several small towns and the infrastructure surrounding them were badly affected with high water levels, debris and reports of bridges being destroyed.

Tropical storm Otto is the southernmost and largest forming hurricane to ever hit the region, Costa Rica hasn't been hit by a hurricane since 1851. According to meteorologists the storm could have been caused by unusually high sea surface temperatures of 29C.
