Meteorologist Guillermo Ramis said in an interview that ”there are conditions of instability high enough so that in a certain region (Rivera, Artigas, Salto, Paysandu and Rio Black) can produce a tornado and added that there are places (Soriano, Colonia, Flores, Florida, Treinta y Tres and Cerro Largo) that can be squalls and even some more severe situation.
Regarding the possibilities of a tornado, meteorologist Diego Vazquez Melo said that those can only be predicted minutes in advance, and only if you have an operating Doppler radar in high resolution mode, dual polarization and with a range of 240 km, a kind of equipment which Uruguay lacks, but alternatively could use images generated by weather radars in Ezeiza and Pergamino, belonging to the National Weather Service of Argentina.
Vazquez Melo predicts for November 1 a cooler, wet, cloudy, windy and very unstable day, with scattered (punctually severe) heavy storms and heavy rains. The general system or southwest winds will rotate and be intensified to strong with very strong gusts.”
