What a difference a day can make in the life of a tropical weather system. Yesterday the forecast showed Dorian gaining strength as a tropical storm and closing in on Cuba by Wednesday. Today's forecast shows the system dying before it can even get that far.

NOAA

NOAA expects Dorian to experience strong vertical wind shear and move through a dry air mass. This should result in Tropical Storm Dorian being downgraded to a tropical wave by early Tuesday morning if not before. This will be our last update unless there is a change in the storms forecast.
