Weather warnings issued for Panama and southern Sonora

Severe weather warnings have been issued across Panama and southern Sonora, Mexico, for the upcoming weekend.

In Panama, the National Civil Protection System (Sinaproc) and the Institute of Meteorology and Hydrology (IMHPA) warned of significant rainfall and storms through Monday, September 7, 2026. The instability is driven by Tropical Wave No. 43, which is expected to cause moderate to heavy rainfall, potential flooding, and landslides. Authorities have advised citizens to avoid crossing rivers or flooded areas and to remain cautious of lightning strikes.

In Mexico, the State Civil Protection Coordination (CEPC) reported that southern Sonora is facing intense storms and strong winds due to strengthened monsoon activity and moisture from the Pacific. The weather is expected to impact mountainous sectors before moving toward regional valleys. Potential hazards include electrical activity, dust storms, and reduced visibility. Local authorities in Cajeme are monitoring high-altitude areas for heavy precipitation.
