Ivette (2016)

A small tropical cyclone formed from a tropical wave and related disturbances in the eastern North Pacific. A broad low formed a few hundred miles south of the southern tip of Baja California Sur, Mexico, and the system became a tropical depression about 650 nautical miles southwest of that point around 0000 UTC on 3 August 2016. It strengthened to Tropical Storm Ivette six hours later and moved generally west to west‑northwest for about five days before weakening and losing tropical characteristics on 8 August as it moved into the central Pacific. The remnant low persisted a few more days and dissipated about 375 miles south of Hilo, Hawaii, by 0600 UTC 11 August.

Ivette did not make landfall. It remained well offshore over the eastern and central North Pacific for its entire life, and no coastal watches or warnings were issued.

Ivette’s maximum sustained winds reached 50 knots (about 58 mph) around 1800 UTC on 5 August 2016, with a best‑estimated minimum central pressure of 1000 mb. That peak corresponds to a moderate tropical storm (below hurricane strength). The storm was very small, with tropical‑storm‑force winds extending at most about 120 nautical miles in diameter.

Because Ivette stayed far from land, there were no measured storm surge reports associated with the storm and no reports of damage. The NHC report lists no rainfall totals for affected cities or counties, and no ships recorded tropical‑storm‑force winds in association with Ivette.

There were no confirmed deaths, direct or indirect, linked to Ivette. The most affected region in terms of proximity was the open eastern and central North Pacific; however, no impacts to populated areas were reported.

Forecasts captured Ivette’s formation reasonably well and official track forecasts were more accurate than recent averages. Intensity forecasts tended to be biased high early on, with several models and official guidance predicting hurricane strength that Ivette never reached; Ivette’s small size likely made it more vulnerable to moderate wind shear than the models anticipated.
