Hurricanes are powerful storms, but they require a tug or pull from other weather systems, such as a cold front or a dip in the jet stream, to determine how fast they move and where they go.
When those influences are very weak or absent, however — as is the case with Melissa — a storm can meander for days, dumping torrential amounts of rainfall on anyone unlucky enough to be nearby.
There is evidence that slow-moving tropical storms and hurricanes are occurring more frequently in the Atlantic Basin, particularly near and over land masses, experts say. Studies in the past several years have showed a slow-down in forward speed at landfall. That’s a critical change, since a slower-moving storm typically means more flooding rainfall, and potentially more storm surge.
Some research has pointed to global warming as a potential cause of this trend, but this is not yet fully established, said meteorologist Kieran Bhatia of the global risk and reinsurance company Guy Carpenter.

Tropical storms transport heat.
The northern latitudes are now warmer.
Things are changing. Look at the 2m temp anomaly of Canada for the next 10 days- blazing red.
