According to meteorologist Sam Lillo, Erin deepened by 70 millibars in 24 hours from Friday morning to Saturday morning. This makes Erin the most rapidly intensifying hurricane, before Sept. 1, ever measured in the Atlantic Ocean.

Hurricane Erin has strengthened to a dangerous Category 5 storm, but remains on track to just send dangerous surf and rip currents to the Jersey Shore.

The August weather might seem ideal for a beach trip, but Hurricane Erin will bring widespread danger in coming days.

Hurricane Erin is bringing heavy rain to the U.S. Virgin Islands on Saturday as the Category 5 storm moves through the Caribbean
