This is a list of unusual tropical cyclones.

Latitude and Longitude records


The easternmost formation of any eastern Pacific tropical cyclone is 1993's Hurricane Greg, which started out as Tropical Storm Bret in the Atlantic and formed at 40°W. If systems that were not continuously a tropical cyclone are excluded, the easternmost east Pacific tropical cyclone is 1971's Hurricane Olivia, which was originally the Atlantic's Hurricane Irene, which formed at 48°W. Excluding cyclones that crossed in from the Atlantic, the easternmost formation in the eastern north Pacific is 2008's Tropical Storm Alma, which formed near 86.5ºW.

The westernmost formation is of Tropical Depression 17W, which formed west of 177°E, before crossing the dateline. Excluding western Pacific systems that cross the dateline, the westernmost formation is Tropical Storm Moke, which formed at 178°W.

The southernmost formation is of Tropical Depression One-C, which later became Hurricane Ekeka. One-C formed at 5°N.

The northernmost formation is Tropical Storm Wene, which formed in the western Pacific at 32°N before crossing the dateline. Excluding dateline crossers, the northernmost formation is of an Unnamed Hurricane in the 1975 season, which formed at 31°N. Both of these latitudes are south of where an unofficial cyclone, the 2006 central Pacific cyclone formed, which was 36°N.

The easternmost longitude a northeastern Pacific tropical cyclone has reached is 84°W. That was the longitude where an unnamed tropical depression went extratropical after crossing into the Atlantic and becoming a tropical storm. Excluding systems that cross into the Atlantic, the easternmost longitude attained by a tropical cyclone in the Pacific Ocean was slightly east of 87°W, by Tropical Depression Adrian.

The westernmost longitude a northeastern Pacific tropical cyclone has attained is 130°E, by Typhoon Oliwa after it crossed the dateline. If it is required that eastern Pacific tropical cyclones stay in the eastern Pacific, the westernmost a tropical cyclone has reached is 179°W, by Hurricane Dot.

The southernmost an eastern north Pacific tropical cyclone has reached is 4°N, by the pre-Ekeka depression.

The northernmost tropical cyclone in the eastern north Pacific is the unnamed hurricane of 1975. It ceased being a tropical cyclone at 54°N.

California

 * After October or before June, 1854- A system considered a tropical cyclone makes landfall just north of the Golden Gate.
 * After October or before June, 1859- A system considered a tropical cyclone makes landfall between Cape Mendocino and San Francisco Bay.
 * September 25, 1939- The 1939 California tropical storm makes landfall in California, killing 45 to 93.
 * September 6, 1972- Tropical Depression Hyacinth makes landfall.
 * September 6, 1978- Tropical Depression Norman makes landfall.

Hawaii

 * August 7, 1958- A tropical storm makes landfall on the Big Island of Hawaii.
 * August 7, 1959- Hurricane Dot makes landfall on Kauai.
 * October 20, 1983- Tropical Depression Raymond makes landfall on Molokai, Oahu, and Kauai.
 * August 3, 1988- Tropical Depression Gilma makes landfall on Maui and Molokai.
 * September 11, 1992- Hurricane Iniki makes landfall on Kauai, killing six throughout the islands.
 * September 14, 1992- Tropical Depression Orlene makes landfall on the Big Island.

Central America

 * June 9, 1936- A tropical storm makes landfall on Guatemala, dropping heavy rainfall before reforming in the western Caribbean Sea.
 * September 28, 1949- A tropical storm moves slowly northwestward into Guatemala. It moves northward and crosses the western portion of the Yucatán Peninsula before entering the Gulf of Mexico.
 * September 20, 1982- Tropical Depression Twenty-Two-E, which later became Hurricane Paul strikes near the border of Guatemala and El Salvador, killing hundreds due to river flooding.
 * June 7, 1997- Tropical Depression Andres makes landfall near San Salvador, El Salvador.
 * May 19, 2005- Tropical Depression Adrian makes landfall on the Pacific coast of Honduras.
 * May 29, 2008- Tropical Storm Alma makes landfall near Leon, Nicaragua.
 * May 30, 2010- Tropical Storm Agatha makes landfall in Guatemala, killing 320 and causing over 1.6 billion (2010 USD) in damage.

East Pacific to West Pacifc


Tropical cyclones passing 140°W are routine events and not notable; the last year that did not happen was 2008. However, very few eastern Pacific proper cyclones that enter the central Pacific make it to the dateline. Only 6 have ever been recorded, and are listed below.

† System ceased to be a tropical cyclone before crossing the dateline and subsequently reforming.

‡ Hurricane/Typhoon Li formed in the eastern Pacific, right at the boundary with the central, but was not named until it crossed into the central Pacific.

Central Pacific to East Pacific


Though many tropical cyclones that form east of 140W pass it and continue into the central Pacific, others going east are very uncommon. This has only occurred twice, and one other time unofficially.

In addition, an unofficial cyclone formed on October 30, 2006 in the central Pacific subtropics. It eventually developed an eye-like structure. Its track data indicates that it crossed from the central to the east Pacific because it formed at longitude 149°W and dissipated at 135°W. NASA, which is not a meteorological organization, called this system a subtropical cyclone, and the Naval Research Laboratory Monterey had enough interest in it to call it 91C. The system has also been called extratropical. This cyclone is unofficial because it is not included in the seasonal reports of either Regional Specialized Meteorological Center.
