Hurricane Isaias was a deadly Category 1 hurricane which impacted the Eastern Caribbean and caused significant damage in the Eastern United States, causing a widespread tornado outbreak and featuring the strongest tropical cyclone-spawned tornado since Hurricane Rita in 2005. The ninth named storm and second hurricane of the 2020 Atlantic hurricane season, Isaias originated from a vigorous tropical wave off the coast of Africa that was first identified by the National Hurricane Center on July 23. The tropical wave gradually became more organized, and obtained gale-force winds on July 28, before organizing into Tropical Storm Isaias on July 30. Isaias marked the earliest ninth named storm on record, surpassing 2005's Hurricane Irene by eight days. Isaias strengthened into a Category 1 hurricane the next day, reaching a peak intensity of 85 mph (140 km/h) and a pressure of 987 mbar. On August 1, the storm made landfall on North Andros, Bahamas and subsequently weakened to a tropical storm before paralleling the east coast of Florida and Georgia. As it approached the Carolina coastline, it reintensified back into a hurricane shortly before making landfall near Ocean Isle Beach, North Carolina, at 3:10 UTC on August 4, and proceeded to accelerate up the East Coast of the United States as a strong tropical storm before transitioning into an extratropical cyclone and dissipating in Quebec.
