Ramon (2017)

A tropical wave that moved off Africa on 21 September crossed into the eastern North Pacific and became better organized south of the coast of southern Mexico. A broad low formed on 2 October and a tropical depression developed at 1800 UTC 3 October about 140 nautical miles southeast of Huatulco, Mexico. The system moved west‑northwest to northwest, briefly became Tropical Storm Ramon on 4 October, and then quickly lost organization in strong upper‑level winds and near the Mexican coast. Ramon degenerated into a trough south of Acapulco by 0000 UTC 5 October and its remnants dissipated the next day.

Ramon did not make any landfalls. Its center stayed offshore south of the Mexican coast while weakening and eventually dissipating; a Tropical Storm Watch was issued by the government of Mexico from Puerto Ángel to Acapulco from 1500 UTC 4 October until it was discontinued at 0300 UTC 5 October.

The peak intensity was estimated at 40 knots (about 46 mph) with a minimum central pressure near 1002 mb, based primarily on ASCAT scatterometer data at 0410 UTC 4 October. That intensity corresponds to a modest tropical storm, and Ramon never reached hurricane strength.

No storm surge or significant coastal inundation was reported in the official record, and the report does not list notable rainfall totals at specific cities or counties. Observations used to track and analyze Ramon included satellite scatterometer data, ship reports, and microwave satellite products, but the storm was short‑lived and its convection remained displaced from the center due to strong northeasterly wind shear.

There were no reported deaths, injuries, or damage associated with Ramon. Ramon was notable chiefly for its short life span and rapid weakening under strong upper‑level shear; genesis was somewhat anticipated in forecasts but short‑range formation probability estimates varied as shear was expected to inhibit development.
