The tropical surge of moisture that has been drenching much of Central America this week will shift northward over the course of this weekend and early next week.
On Saturday, heavy downpours will continue across Guatemala and western portions of El Salvador.
Portions of Mexico will be next in line for the threat of heavy rain, flooding and mudslides.
“Bouts of heavy rain and thunderstorms will shift into southern and eastern Mexico later this weekend and early next week,” AccuWeather Senior Meteorologist Rob Miller said.
Any thunderstorms can also produce locally damaging winds, but these will be isolated cases. Widespread strong winds are not expected.
In these places, 150-300 mm (6-12 inches) of rain is expected from Saturday to Tuesday, with an AccuWeather Local StormMax™ of 450 mm (18 inches). The heaviest rainfall amounts will likely be over the Mexican state of Veracruz and southern portions of Tamaulipas.
This area of heaviest rain includes the cities of Tampico and Veracruz, where a month’s worth of rain could fall in just a few days.
Tampico averages nearly 200 mm (7.85 inches) of rain during the month of June, while Veracruz averages 114 mm (4.50 inches) of rain.
“Flash flooding will be possible from Tampico to Veracruz and into the nearby mountains,” Miller said.
This amount of rain over such a short period of time will be enough to cause flooding and mudslides and could wash out roads and bridges in some places. Travel delays are also expected.
