Ramon (2023)

A small tropical cyclone formed from a disturbance in the monsoon trough just west of Central America in mid-November and is analyzed to have become a tropical depression by 1200 UTC 21 November 2023. It moved slowly and meandered over the west‑central eastern Pacific through the rest of the month, reaching tropical storm strength late on 24 November and weakening and dissipating by 27 November. Ramon’s development was the latest tropical-storm formation in the eastern Pacific since 1983.

Ramon did not produce any coastal warnings and there were no reports of it making landfall. No ship or land reports of tropical-storm‑force winds were received during its life, and it remained over open water throughout its existence.

The cyclone’s peak intensity was estimated at 40 knots (46 mph) with a minimum central pressure of 1002 mb, reached from 1800 UTC 25 November into 0000 UTC 26 November. At peak strength Ramon was a moderate tropical storm (below hurricane strength).

Measured storm surge and rainfall impacts were negligible in the coastal observational record: there were no reports of storm surge impacts and no stations recorded tropical-storm‑force winds. The report lists no notable rainfall totals or coastal inundation at specific cities or counties associated with Ramon.

There were no confirmed deaths or reports of damage associated with Ramon. The storm produced little to no direct impacts on land.

Noteworthy aspects include Ramon’s late-season timing — the latest eastern Pacific tropical storm since 1983 — and the difficulty in forecasting its formation: early outlooks gave only a low chance of development many days before genesis. Official track and intensity forecasts performed reasonably well overall for the forecasts issued.
