Panama Issues Rain Alert as Dry Spell Ends, Thunderstorms Expected Through July 3

Panama is bracing for a significant increase in rainfall and thunderstorms as the "veranillo de San Juan" dry period concludes. The Institute of Meteorology and Hydrology of Panama (Imhpa) has issued a national vigilance alert, effective from June 30 to July 3, 2026, warning of moderate to heavy precipitation across the entire country and both maritime sectors.

The shift in weather patterns is attributed to rising humidity levels and the arrival of new atmospheric systems. Imhpa forecasts daily rainfall between 25 and 85 millimeters, with potential 72-hour accumulations reaching 75 to 255 millimeters, depending on the region. This increased moisture content and changes in wind flow are expected to foster the formation of rain, electrical storms, and possible wind gusts.

Adding to the instability, Tropical Wave No. 19 is projected to enter Panama between July 1 and 2, further reinforcing atmospheric instability alongside low-pressure systems and trough axes. Imhpa cautioned that these conditions could lead to a significant rise in river and stream levels, as well as an increased risk of landslides and urban and rural flooding, particularly in vulnerable areas. The public is urged to remain attentive to official bulletins and follow the guidance of civil protection agencies.
