The Center for Weather and Climate Research Applied to Agriculture (Cepagri) of the State University of Campinas (Unicamp), defined the phenomenon that hit the São Paulo city of Campinas on Sunday morning as a Microburst.
The phenomenon has a destructive power similar to a tornado. At least 70 trees fell and houses were left without roofs with streets flooded. 100,000 properties remain without power.
Ana Avila, director at Cepagri said:
The Microburst is more violent than a tornado. The curious thing is that they do not usually happen this time of year.
Data provided by the Brazilian Network of Lightning (BrasilDAT) showed that 1,450 lightning strikes were recorded during the storm.
A photographer Ana Carolina Alves commented on the intense lightning show:
It was almost 25 minutes without interruption. I've never seen anything like it, it was amazing.(translations by Google)
Living here in Campinas, I can say that the weather here is still with HEAVY RAIN...
and thunders as I never hear and Saw in my Life...
But the worst is not over (future) yet!!!.
