Weather Watch: Changes Ahead 04-09 to 04-12

Updated Fri Apr 10th 2026, 3:16am PDT | Forecast for 04-09-2026 to 04-12-2026

Tropical Storm Belt — We're keeping an eye on some notable weather changes coming this way from April 9th through April 12th. In Mexico and North Central America, watch out for an upper-level trough bringing increased rain chances and possibly severe weather on Saturday. Meanwhile, the Caribbean is seeing a front move slowly through, leading to some showers particularly by the weekend. Over in South America, the West Amazon Basin and Colombia are set to experience increased rainfall with the influence of the Bolivian High.

What's Happening in Mexico and North Central America?

Expect zonal flow, or a west-to-east movement in the upper atmosphere, on Thursday and Friday, with some smaller disturbances leading to light rain across Mexico. On Saturday, a larger weather system moves into the western United States, breaking down pressures in the north and central U.S., and sending moist winds into eastern Mexico. This is likely to lead to heavier rain and a risk of severe storms in areas like north Coahuila, Nuevo Leon, and Tamaulipas.

Caribbean and The Bahamas: Weekend Showers

A ridge, or high-pressure area, dominates much of the Caribbean on Thursday, limiting strong storm development. However, a front is pushing through the Bahamas, moving southward by Friday into Cuba and developing a weak shear line around Hispaniola. Expect some rain in these islands, especially as we head into the weekend.

Rainy Days in Northern South America

The powerful Bolivian High affects the weather with more rain likely in the West Amazon Basin and Colombia. Troughs, or low-pressure areas, moving through on Thursday will increase rain chances by Friday and Saturday. These systems bring moisture and strong winds, enhancing rain over the region, particularly in the Amazon.
