What happens to the storms when they leave the US? Do they fizzle out, come back around, and hit us again? What happens?
Dave Seastrom, Lisle
Low-pressure systems generally have life cycles that range from a few days to, on rare occasions, several weeks. They can travel thousands of miles, but not around the world. During a typical life cycle, the low forms, intensifies, matures, and then dissipates, often becoming absorbed in the circulation of larger or newly formed low-pressure systems. Low-pressure systems that enter the U.S. on the West Coast usually redevelop as they cross the Rockies, then dissipate or become assimilated in another low-pressure area. Atlantic hurricanes have been tracked to northern Europe, transforming into strong, non-tropical storms accompanied by heavy rains and high winds.
