According to the National Oceanic and Atmospheric Administration (NOAA)/Cooperative Institute for Research in the Atmosphere (CA) on November 17th, strong winds swept across the southern Argentine plains, carrying sand and dust.

On Monday, a strong storm hit southern Argentina damaging several fishing boats in multiple ports in the region, with three small vessels sinking in the port of Caleta Olivia in Santa Cruz Province.

According to the Argentine government's meteorological service, a low-pressure system from the Pacific caused air currents to climb over the Andes Mountains, with wind speeds reaching above 80 knots in parts southern Argentina. The strong waves from the Atlantic Ocean severely impacted small boats docked in ports with weaker protection. According to Revista Puerto, three boats named Yakisa, Baruda, and Alborada sank one after the other in the port of Caleta Olivia. There have been no reports of casualties, and the Argentine Navy is working with boat owners and other agencies to arrange for the salvage of the sunken vessels.

Another small boat, the Mother Teresa, took on water and partially sank in ayard in Rawson, Chubut Province.

In the port of Puerto Deseado in the northeast of Santa Cruz Province in Patagonia, the strong winds a vessel from its moorings, causing it to crash violently into another boat. The fishing boat Atlantico I collided with the squid boat Soho Maru, a hole in the latter's bow. There have been no reports of casualties or pollution.

As of Tuesday, eight provinces in Argentina remained under "yellow alert", with wind speeds reaching up to 40 knots in the southern Patagonia region.
