Sandra 30th Cat3+ Or Higher N. Hemisphere Hurricane This Year; Prior Records 23 In 1997, 2004
Sandra became the latest Category 4 hurricane of record early Thursday morning in either the eastern Pacific or Atlantic basins.
In other words, Sandra is the strongest hurricane so late in the season. Only three other eastern Pacific storms have formed later in the calendar than Sandra in records dating to 1949.
Hurricane Sandra became the second latest forming hurricane on record, behind Hurricane Winnie in 1983.
There is no record of an intact depression or named storm making a landfall on either Baja California or Mexicos Pacific coast so late in the season. According to hurricane specialist Michael Lowry, the latest eastern Pacific landfall on record was Tara on November 12, 1961. So, Sandra is likely to shatter this record by over two weeks.
The previous latest major hurricane in either the central-eastern Pacific or Atlantic was an unnamed storm in 1934, that remained a major hurricane into Nov. 23.
The previous latest Category 4+ tropical cyclone in either the eastern Pacific or Atlantic basins was Hurricane Kenneth on Nov. 22, 2011.
Sandra is the 30th Category 3+ tropical cyclone of the year in the Northern Hemisphere, far exceeded the previous record of 23 such storms in 1997 and 2004.
