Hurricane Erin’s intensification was extraordinary, with an 85 mph jump in just 24 hours. That makes it one of the fastest Category 1 to Category 5 transitions ever recorded in the Atlantic. It even slightly surpassed Hurricane Lee’s 2023 leap of about 80 mph in 24 hours, placing Erin in rare company.

Over the weekend, northern portions of the Leeward Islands, the Virgin Islands, and Puerto Rico are expected to receive tropical rain ranging from 2 to 4 inches, with isolated totals up to 6 inches. Flash flooding, landslides and mudslides will be the main concerns over the next several days.

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

Hurricane Erin became the first hurricane of the 2025 Atlantic season on Friday, with sustained winds of 75 mph as it moves toward the Leeward Islands.
