Tropical Depression Three slams Mexico, strengthening possible

Tuesday, June 2nd 2020, 11:14 am - The storm is fuelled by remnants of Tropical Storm Amanda in the Pacific, which caused at least 20 deaths in central America over the weekend.

A powerful tropical cyclone, fuelled by moisture from a dissipated tropical storm, has parked itself in Mexico's Bay of Campeche, set to bring continuous and extreme rainfall over the coming days.

Tropical Depression 3 formed late Monday in the bay -- right on schedule for the "official" June 1st start to the Atlantic hurricane season. It's being bolstered by the remnants of what had been Tropical Storm Amanda, which slammed into Guatemala and Central America in recent days before tracking into the Bay of Campeche and restrengthening.

The storm is expected to bring, and possibly exceed, 500 mm of rain to the worst-hit areas of the region, with lesser amounts elsewhere, though still amounting to hundreds of millimetres of rain.

As for what's ahead, some strengthening is expected, but Weather Network meteorologist Dr. Doug Gillham says the storm's long-range future is uncertain.

TD3 track

"One scenario is that the storm goes ashore and dissipates, though with that scenario it is also possible that a second storm develops offshore," Gillham says. "However, if TD3 does not dissipate later this week, then we are concerned that the storm will strengthen as it tracks north across the Gulf of Mexico, with a significant threat for it to become a hurricane before making landfall along the western or northern Gulf coast (Texas or Louisiana)."

Should the storm cross the threshold to become a tropical storm, it will become the third named storm, Cristobal, of a season that is being forecast as above average.

Tropical Storm Amanda, which impacted Guatemala, El Salvador and much of Central America over the weekend, brought extreme rainfall amounts. Reuters reports at least 20 people have been reported killed amid flooding and landslides. Hundreds of homes were also reported destroyed.
