September 20

1971: Having weakened after making landfall in Nicaragua the previous day, Hurricane Irene regains enough strength to be renamed Hurricane Olivia, making it the first known hurricane to cross from the Atlantic Ocean into the Pacific.

1978: Hurricane Greta, after having weakened to a tropical depression due to its passage over Central America, restrengthened to a tropical storm in the far eastern Pacific Ocean. Because naming conventions for tropical cyclones in the Pacific are different from the Atlantic Ocean, the storm was renamed "Olivia", becoming a rare two-name storm.

1995: Hurricane Juliette, the strongest hurricane of the 1995 Pacific hurricane season, reached peak intensity over the open ocean, with maximum sustained winds of 150 miles per hour (240 km/h).

2010: Typhoon Fanapi made landfall in Fujian, China, killing 100 people.

2017: Hurricane Maria, one of the strongest Atlantic hurricanes on record, made landfall on Puerto Rico near its peak intensity, killing 64 people directly and causing catastrophic damage that left the entire island without power. This lack of power would eventually lead to 3,000 more deaths in the coming months.
