Inmet issues danger alerts for 78 cities in the state due to the formation of a low pressure system and cold front
AI-generated summary
The state of Paraná faces climate instability caused by the formation of an extratropical cyclone and the advance of a cold front.
After a Sunday (1) with storms that caused damage in several cities in the state, the week should continue to record storms in different regions of Paraná.
The reasons are the formation of an extratropical cyclone on the coast of southern Brazil, the increase in temperatures and the shock with the advance of a new cold front, according to the Environmental Technology and Monitoring System (Simepar).
The state is under orange storm alert from the National Institute of Meteorology (Inmet) this Tuesday (3), but the forecast is that the weather events will become even more intense in the following days.
For Wednesday (4), Inmet issued a red alert for the south of the state, which is the most serious of all. It indicates great danger of storms with rain exceeding 60 mm/h or greater than 100 mm/day, winds of more than 100 km/h and hail, and is aimed at 78 cities.
Simepar adopts a table to interpret the strength of storms. If in a period of 6 hours it rains less than 0.2 mm, the rain is not even considered. Between 0.3 mm and 2.5 mm is considered a drizzle. It becomes light rain when the accumulation in 6 hours is between 2.5 mm and 10 mm. From there up to 25 mm, the rain is moderate. From 25 mm to 50 mm is considered heavy rain, and above 50 mm is considered extreme rain.
Julia Munhoz, meteorologist at Simepar, explains that this Tuesday (3) the weather remains hot and humid, with highs above 25°C across the state, and that from the afternoon onwards isolated rain showers accompanied by lightning may develop, with the possibility of localized storms.
On Wednesday (4), the risk scenario increases. The intensification of this low pressure system keeps the weather unstable and favors strong warming, especially in the northern half of Paraná, where temperatures can approach 35°C. Throughout the day, rain may occur in all regions, with greater concentration and risk of intense storms in the southern half of Paraná, including the possibility of the formation of supercells.
The meteorologist states that the storms will continue on Thursday (5), when an extratropical cyclone forms on the coast of southern Brazil, accompanied by the advance of a cold front through the states of the region.
With the movement of this system, storm areas tend to advance from the southern half towards the northern half of Paraná, where there is a possibility of potentially severe storms, highlights Julia.
On Friday (6), with the strong warming in the western half of Paraná, isolated rain showers may still occur, accompanied by lightning.
Due to this week's risk scenario, Simepar recommends that the population register to receive alerts from the State Civil Defense. Just send an SMS from your cell phone with your zip code of residence to the number 4199, alert.
In case of emergencies, information must be consulted with the Civil Defense (telephone 199) and the Fire Department (telephone 193). Problems related to power cuts and fallen poles must be reported to Copel (telephone 0800 51 00 116).
