According to Brazilian private forecast company MetSul a new extratropical cyclone affecting the south and east of Uruguay is to be expected. On Tuesday November 1 there will be lots of rain and storms in several cities with volumes of 50 mm to 100 mm in a short period of time in some places and heavy storms with strong winds and localized hail, while warned that a new extratropical cyclone formed in eastern Argentina and will cause strong winds for several hours in the south and east of Uruguay with speed of 60 km / h to 80 km / h and higher gusts of 80 km / ha 100 km / h on November 2.
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.”
