A wave of upper level energy, arriving well ahead of a vigorous trough of surface and high level low pressure, acted on a very unstable airmass that was also conducive to producing rotating thunderstorms during the pre dawn hours of October 30th to produce a mini supercell thunderstorm in northern Cameron County, which raced northward through Willacy and into Kenedy County. The thunderstorm, spawned a brief tornado around Los Coyotes just after 630 AM, which moved to the north northwest and quickly dissipated before reaching Raymondville. A second tornado formed to its east, at a Cotton producing facility in Willamar.

A survey team revealed peak winds ranging from 74 to 86 mph for the Los Coyotes Tornado. The 86 mph winds were measured by a property owner’s weather station, whose information was considered viable based on visual evidence of damage and radar depiction of velocity in the core of the circulation, which exceeded 60 knots (70 mph). Damage in Los Coyotes was to a few barns and outbuildings, as well as uprooted and snapped trees. Emergency Management noted seven power poles were leaning or down, but had been repaired by the time to survey was conducted on October 31.

The survey team estimated peak winds between 70 and 75 mph for the Willamar tornado. Primary damage was a cotton seed container/holder that was lifted from moorings into concrete block. The lack of material in the metal container allowed winds to get underneath and lift; pressures on the minimally anchored columns caused the damage. Other damage included a portion of roof peeled back from a mobile home, where a 12 year old child was injured by flying debris and taken to a local hospital in Harlingen for observation. The tin roof damage revealed poor connections to rotted wood. Minor damage to trees along Farm to Market Road 1420 was also noted.
