Tropical Storm Emily is heading across the Caribbean. Better shutter the windows, stock up fresh water, and if you are vacationing in the D.R., Bahamas or Turks and Caicos, you may wish to cash in that travel insurance.
So summer vacations in the tropics are always a gamble. In 2009, I made travel plans about a week out since hurricanes move slowly, say 15-25 mph.
Should Emily pick up, you can download GIS tracking data.
