Following yesterday's warnings, Argentina's National Meteorological Service (SMN) issued orange and red alerts for extreme temperatures on February 19, 2026, in northern cities: orange for Formosa and red for Corrientes and Resistencia amid the ongoing summer heatwave.
Building on the red alerts for Resistencia (Chaco) and Corrientes, plus orange for Formosa issued on February 18—as covered in prior updates—the SMN extended high-risk warnings into Thursday, February 19, 2026.

Published in the final hours of February 19 per TN reports, these alerts highlight health and activity risks from intense heat in northern Argentina.
