Satellite imagery shows only inside the current NHC forecast cone; everything else is a quiet gray map. Pick a storm on the left to move the spotlight. The Home button returns to the cone.
When no storm is active, the spotlight shows NHC's 7-day potential development areas instead.
Counties are shaded by their highest NWS tropical watch or warning; hover one to see every alert in effect there in the right panel.
Numbers refresh every 10 minutes from NHC. Always check the official NHC advisory before acting.
