Mexico faces severe flooding from not only the Atlantic's Tropical Rainstorm Ingrid, but also Tropical Rainstorm Manuel from the eastern Pacific.
Manuel is currently riding along the southwestern Mexican coast, while Ingrid made landfall near La Pesca, in northeastern Mexico Monday Monday morning and was drifting inland Monday night.
Both pose a major threat to lives and property by unleashing torrential rain. Intense rainfall on the landscape will lead to major flash flooding and the risk of mudslides. Locally strong winds will also accompany each storm onshore.
While northeastern Mexico bears the brunt of Ingrid, South Texas will experience benefits and adverse impacts from the storm.

A disaster is potentially in the making across northeastern Mexico where Ingrid threatens to drop 8 to 16 inches of rain through Tuesday night across the states of southern and central Tamaulipas, southern Nuevo Leon and southeastern San Luis Potosi.

Localized amounts of 20 to 30 inches could fall on the higher elevations of the Sierra Madre Oriental.
Some of these same areas have already endured flooding in recent weeks from Tropical Storm Fernand and Tropical Depression 8, according to AccuWeather.com Expert Senior Meteorologist Alex Sosnowski.

Ingrid made landfall just north of Tampico on Monday with hurricane force wind gusts just north of the center.
A coastal water inundation of 1 to 3 feet with was most likely occurring along central coast of Tamaulipas, immediately to the north of where Ingrid moved onshore. However inundation may have been locally higher to as much as 6 feet. Coastal flooding is a concern northward to the central Texas coast.
As Ingrid churns towards the coast, seas will remain rough for small craft and swimmers across the western Gulf of Mexico.

On the other side of Mexico, Manuel continued to weaken. Manuel was downgraded to a tropical depression Sunday evening after making landfall. During Monday morning, Manuel was a tropical rainstorm. Manuel is forecast to unleash widespread rainfall totals of 5 to 10 inches across the states of Guerrero, Michoacan, Colima and southern Jalisco through Monday. This includes the city of Manzanillo.
Some coastal and mountains areas east of Manuel's landfall site--which is just west of Lazaro Cardenas--will see rain totals approach or exceed a foot.
Acapulco has already picked up nearly 12 inches of rain in the past 48 hours, ending at 8 a.m. Sunday EDT.
Heavy rain will spread back to the east along Mexico's southern coast Tuesday and Wednesday as tropical moisture from the Pacific is drawn toward the center of Ingrid.
