Tropical Storm Boris 2026

Live tracking map, satellite, radar, and forecasts of Tropical Storm Boris 2026 near Guerrero, Mexico. Current wind speed 45mph.

Heavy rainfall associated with Tropical Storm Boris will impact portions of southern Mexico. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain.

Tropical storm conditions are expected to reach the coast of southern Mexico within the Tropical Storm Warning area tonight or early Tuesday.

An ASCAT overpass revealed that the center of the storm, although still somewhat elongated, is located to the south of the previously estimated track. Therefore a special advisory is being issued to relocate the center farther offshore of the coast of Guerrero, Mexico. Based on this relocation, the landfall time has been delayed.

Also, data from the scatterometer overpass indicated that the intensity needs to be adjusted slightly to 45 mph (40 knots). Since the system remains disorganized, however, little change in strength is anticipated before landfall.

The threat of very heavy rainfall continues to be the primary hazard of concern, which should result in flash flooding and mudslides in mountainous terrain.

This special advisory is being released in lieu of the 18:00 UTC intermediate advisory.
