Tropical Storms Barry And Flossie Forecast To Form In Southern Gulf, Eastern Pacific. Warning Issued In Mexico.

The tropics have quickly come to life on either side of Mexico, and that is forecast to generate two named storms, Barry and Flossie, in the next day or so.

– The big picture: A large pocket of moisture is pushing westward through Central America and the eastern Pacific, within which there are two systems that are expected to develop. Direct impacts by a tropical system in the United States are not expected, but some moisture could reach the Southwest late in the week ahead.

– Gulf system: Previously known as Invest 91L, this was designated Tropical Depression Two by the National Hurricane Center Saturday afternoon. It is producing thunderstorms over parts of southeastern Mexico and the Bay of Campeche.

A tropical storm warning has been issued along parts of eastern Mexico’s Gulf Coast from southern Tamaulipas to northern Veracruz states, including Tampico. This means tropical storm conditions are expected in these areas, in this case, Sunday into Sunday night.

It is forecast to gain enough strength to become Tropical Storm Barry, the second storm of the 2025 Atlantic hurricane season. But it doesn’t have a long runway before it comes ashore in eastern Mexico by late Sunday or early Monday.

Locally flooding rainfall is likely the main threat with this system. Parts of eastern Mexico, especially near Tampico, could pick up 3 to 6 inches of rain, with isolated amounts of 10 inches, according to NOAA’s Weather Prediction Center. Tropical storm force winds, some elevated surf and rip currents can also be expected along eastern Mexico’s Gulf Coast.

– Pacific system: Invest 95E is expected to develop into Tropical Storm Flossie in the next day or so as it moves northwestward near or offshore of the Mexican coastline. Most computer models suggest Flossie may top out either as a tropical storm or low-end hurricane. While the forecast is still uncertain, some outer bands of rain may soak areas near Mexico’s Pacific coast, leading to flash flooding. Rip currents and high surf will also likely eventually develop. Tropical moisture from this storm could be sucked northward as a burst of monsoonal moisture into the Southwestern US before July 4th.
