Tropical Storm Mario to Bring High Humidity, Scattered Showers and Storms to San Diego County

Following a hot and dry start to the week, humidity and rain chances climb starting Wednesday in San Diego County as a post-tropical storm sends clouds and showers across Southern California. Tropical Storm Mario has been brewing over the eastern Pacific Ocean, moving north for days now. As it nears the Southwestern edge of the country, it will send its decaying outer bands of dense clouds and at times some rain toward us.

Tropical Cyclone Mario made the transition from a Tropical Storm on Tuesday morning to a Tropical Depression on Tuesday afternoon. On Tuesday night, Mario officially became a post-tropical system as it weakened in cooler ocean waters. It is churning in the Eastern Pacific as a strong low-pressure system.
