RS must face first wave of storms under El Niño

The week started with a cold air mass still covering most of RS, but the arrival of a very hot air mass from Wednesday (15/7) should form the first areas of instability. These conditions may persist until the following Tuesday (21), but some projections indicate the possibility of instability continuing until the end of next week.

The storm sequence is expected to result in between 100 mm and 200 mm of rain accumulated in several municipalities in Rio Grande do Sul. In some isolated areas, these volumes can reach up to 300 mm. As Exame pointed out, the accumulated highs increase the risk of flooding in urban areas, overflowing of streams and streams, in addition to rising river levels and the occurrence of flash floods.

“There will not be the characterization of a heat wave (…) because the hot air will stimulate rain and storms on several days, avoiding some more extreme highs, but depending on the location there will be some days of very high temperatures and above 30oC with severe sweltering”, warned MetSul. Correio do Povo also shared this information.

The storm that hit Eldorado do Sul, in the metropolitan region of Porto Alegre, last Saturday (11) left at least 720 people homeless. With winds of up to 45 km/h and hail, the storm caused damage, ripping off roofs, knocking down trees and leaving thousands of residents without electricity and water. Classes in the municipal education network were suspended. CNN Brasil, Estadão, g1 and Metrópoles, among others, provided more details.
