Current Storm Status and Movement
Ivo maintains maximum sustained winds of 40 mph (65 kph) and was recently centered approximately 195 miles (310 kilometers) south-southeast of Acapulco, according to the National Hurricane Center. The storm continues to move quickly to the northwest at 19 knots on the south side of a strong mid-level ridge situated over the southwestern United States.
Weather experts note that the tropical-storm-force winds associated with Ivo are expected to remain offshore of the coast of Mexico, however heavy rain and rough surf are likely along portions of the southwest coast of Mexico.
Rainfall and Flooding Concerns
The National Hurricane Center warned that Tropical Storm Ivo is forecast to bring total rainfall of 2 to 4 inches—reaching up to 6 inches in certain locations—across parts of the Mexican states of Guerrero, Michoacán de Ocampo, and Colima through Friday, raising the risk of flash flooding.
The storm formed on August 6, 2025, off the Pacific coast of Mexico, bringing the threat of flash flooding to the Mexican states of Guerrero, Michoacán, and Colima. Authorities have been monitoring the situation closely as heavy precipitation continues to affect these coastal areas.
Safety Warnings and Coastal Impacts
National Hurricane Center meteorologists warned of life-threatening impacts as the storm is expected to strengthen. The primary concerns include dangerous surf conditions and the potential for rip currents along Mexico’s Pacific coastline.
Tropical Storm Ivo formed Wednesday along Mexico’s southwest coastline and produced heavy rainfall and rough surf. Coastal communities have been advised to exercise extreme caution near ocean waters due to hazardous conditions.
- Life-threatening surf and rip current conditions
- Flash flooding in low-lying and mountainous areas
- Heavy rainfall accumulations of 2-6 inches
- Rough seas affecting marine activities
Storm Characteristics and Forecast
The last closed isobar has a pressure of 1012 mb, with the radius of 34 knot winds extending approximately 30 nautical miles in the northeast quadrant. This compact storm structure means that while the most intense winds remain offshore, the rainfall and surf impacts extend over a broader area.
According to the latest National Hurricane Center advisory, tiny Ivo continues moving quickly west-northwestward. The storm’s small size and rapid movement have been notable characteristics throughout its development.
Regional Impact Timeline
The storm’s timeline shows a progression of impacts across Mexico’s Pacific states:
- Wednesday: Formation and initial coastal approach
- Thursday-Friday: Peak rainfall and surf conditions
- Weekend: Gradual movement away from the coastline
Tropical Storm Ivo is expected to dump considerable rain on coastal Mexican states throughout Thursday and through Friday. Weather officials continue monitoring the system’s progress as it moves further offshore.
Residents and visitors in affected areas should stay informed about changing conditions and heed all safety warnings from local authorities. The combination of heavy rainfall and dangerous surf conditions requires continued vigilance along Mexico’s Pacific coast.
