It's late in the season, but Kenneth strengthened into a tropical storm in the eastern Pacific Sunday afternoon.
By Monday, it was a hurricane, and by the morning hours on Tuesday it had become a major hurricane with Category 4 strength.
“It's been 27 years since a named storm has formed this late in the eastern Pacific,” says Rob Davis, a meteorologist at The Weather Network. “And this is the strongest late-season hurricane in the eastern Pacific's history of storms.”
The storm was downgraded to a Category 1 storm Wednesday and weakened to a tropical depression by the early morning hours on Friday. No coastal watches or warnings are in place.
While tropical activity at this time of year is unusual, the hurricane season doesn't officially end until November 30.
