--November is the last month of meteorological autumn in the Northern Hemisphere. --Thunderstorms move from the west at higher latitudes, and from the east in the tropics. --Daily thunderstorms form over Cuba, Hispaniola, and Central America throughout the month. --An intermittent equatorial trough, also called the Intertropical Convergence Zone, is in an east-west alignment over the eastern North Pacific Ocean and western Atlantic. --Thunderstorms are frequent over Central America until they are almost absent starting on the 25th. --Lightning is almost absent in Canada. ~Ron Holle
