Teresina and 188 other cities are on alert for low air humidity around 20%

Portal O Dia14 September 2026 at 10:32

Teresina and another 188 cities are under a potential danger alert for low air humidity, with indices that can reach 20%. The weather warning is valid for this Monday (14th), from 10am to 10pm.

According to the National Institute of Meteorology (INMET), relative humidity can vary between 30% and 20% during the alert period. This condition represents a potential risk to the health of the population in the affected regions.

The alert covers several cities, with Teresina being one of the main capitals included in the warning. Meteorological authorities recommend that the population take special precautions during the low humidity period, such as increasing fluid intake and avoiding prolonged sun exposure.

This type of alert is common during drought periods and high temperatures, when water evaporation in the air increases significantly, reducing relative humidity levels. The population in the affected areas should pay attention to the recommendations to minimize health risks.

Why this matters

Residents of Teresina and the 188 affected cities face health risks caused by dry air, including respiratory problems and dehydration, requiring preventive measures during the alert period. The humidity forecast between 20% and 30% indicates severe conditions that can mainly impact vulnerable groups such as children, elderly people, and those with respiratory diseases.
