Meteorologists Track Atlantic and Pacific Tropical Storms

According to a report updated on September 19, 2026, meteorologists with The Weather Company are monitoring multiple potential tropical threats in the Atlantic and Pacific oceans as the 2026 hurricane season continues. Strong wind shear from atmospheric conditions is disrupting cyclone development in the Atlantic by altering wind speed and direction at different heights. Additionally, dry air plumes streaming from Africa's Sahara Desert create unfavorable growth conditions across shaded brown regions of the basin due to suppressed thunderstorm formation. Forecasters are evaluating seasonal activity against historical averages using Accumulated Cyclone Energy, a metric measuring energy produced based on intensity and duration. In the Pacific, Tropical Depression 15-E has reemerged and is heading toward Hawaii with potential for heavy rainfall in flood-fatigued areas. Hurricane Polo has rapidly intensified to Category 5 strength and poses serious concern as it tracks close to parts of southwestern Mexico's Pacific coast late Wednesday into Thursday, bringing risks of flooding rain to the southern Baja Peninsula over the next five days.
