Hurricane Ilsa

On August 18th, a tropical depression formed south of the Gulf of Tehuanapec. It moved westward, and after four days, Ilsa reached its peak of 90 mph over the open Eastern Pacific. It continued west-northwestward, and was absorbed by a cold core upper level. That triggered the development of an unnamed hurricane. August 18 is the 230th day of the year (231st in leap years) in the Gregorian calendar. ...

Hurricane 12

This cyclone, officially known as Hurricane 12, was a bizarre storm. It developed at high latitude and became a hurricane at higher latitude. It is the farthest north an Eastern Pacific tropical cyclone has ever been in recorded history.

A cold core low absorbed the remnant circulation of Hurricane Ilsa on September 2, 1975. Convection increased rapidly, and by the 5th, it had enough convection to be called a tropical depression. This system was located 800 miles northeast of Honolulu, Hawaii. It moved westward, reaching tropical storm strength the next day. It began to move rapidly northeastward. An eye was evident at this time, but it was not until it reached 40º north on the 4th did it become a hurricane. On September 4, a ship reported hurricane-force winds. The storm weakened to a tropical storm on the 5th, and became extratropical that night, located less than 300 nautical miles southwest of Juneau, Alaska. The extratropical low moved southeastward, retaining its identity until it reached Montana, where it was absorbed by a front.

It is not known why this hurricane went unnamed. Any statement about why is purely speculative at this point.

Hurricane Katrina

Hurricane Katrina was the second strongest hurricane of the season, reaching top winds of 135 mph winds on September 3 without affecting land. September 3 is the 246th day of the year (247th in leap years). ...

Hurricane Olivia

Hurricane Olivia was the strongest landfall of the season. A tropical storm formed on October 22nd south of Mexico. It moved northwestward initially, followed by a northeast turn. Olivia then intensified steadily. It reached Category 3 intensity and a peak of 115 mph winds just before landfall. On October 25, Olivia smashed ashore close to Mazatlan. Olivia was the strongest landfall since 1959. October 22 is the 295th day of the year (296th in leap years) in the Gregorian Calendar, with 70 days remaining. ...
