Severe Flooding to Continue Across Colombia

Severe Flooding to Continue Across Colombia

Tropical moisture from both the Pacific and the Atlantic will help to fuel the flooding rainfall through early in the week.

The death toll across Colombia continues to rise after weeks of excessive rainfall has produced widespread flooding throughout the nation. The death toll stands at 136 lives.

Government officials on Thursday declared a state of calamity in 28 of the nation's 32 states. More than 1.2 million people have been affected by the flooding across the nation.

More rain is likely over the next few days, any of which will aggravate the flooding currently ongoing across the nation.

Colombia is the meeting point between two tropical air masses; one originating from the Atlantic Ocean and one originating from the Pacific Ocean. While this is the rain season for Colombia, it has been enhanced by the onset of La Nina, which typically produces more rain than normal across northern South America.

Rain Sunday through Tuesday will be heaviest over the Andes mountains, which span much of western Colombia from Ecuador to northwest Venezuela, where the two tropical air masses collide. Numerous showers and thunderstorms will develop, any of which will produce daily rainfall totals in excess of 2-4 inches.
