Maybe this is one of Fidel's insane experiments gone awry-- an attempt to prolong his life through climate change.  Maybe not.  But you can be sure that it will be blamed on the U.S. and on the "blockade."

Rare cold front chills Cuba

An unusual cold front chilled parts of Cuba Monday as the temperature dropped to as low as four degrees Celsius, (39.2 Fahrenheit) Cuba's Meteorology Institute (Insmet) said.

The Caribbean island country, which usually enjoys balmy temperatures of 22 to 28 degrees Celsius  (71.6 to 82.4 F) all year around, saw the thermometer dip to single-digits at various locations early Monday due to a "cold, dry Arctic air mass" over it.

Insmet said on its website that 20 meteorological stations in Cuba registered temperatures lower than 10 degrees Celsius and it was "notably cold" in towns located in the central and western regions.

The lowest temperature registered was four degrees in Bainoa, 45 kilometers west of Havana, while Cuba's capital registered a cold 11.9 degrees Celsius (53.2 F), a rare occurrence in a city where the temperature seldom drops below 17 degrees (62.6 F).

"In the western and central regions, the lowest temperatures were between 10 and 13 degrees Celsius and in the eastern region, they were 19 degrees," said Insmet, noting the temperature in eastern Cuba never goes below 25 degrees (77 F).
