Tropical Storm Ingrid made landfall in La Pesca located in northeastern Mexico on Monday, Sept. 16. NASA’s TRMM satellite found heavy rainfall occurring in the storm before its center made landfall.  A tropical storm warning is in effect for Cabo Rojo northward to Rio San Fernando.

NASA’s Tropical Rainfall Measuring Mission or TRMM satellite passed over Tropical Storm Ingrid on Sept. 16 at 0227 UTC/Sept. 15 at 10:27 p.m. EDT and measured its rainfall rates from space. Some of the heaviest rainfall was occurring in the center of the storm at a rate of over 2 inches/50 mm per hour. TRMM measured rainfall beginning from as high as 14 km, so cloud tops are higher than that.

On Sept. 16 at 8 a.m. EDT, Ingrid’s maximum sustained winds have decreased from hurricane-force to near 65 mph/100 kph and additional weakening is forecast as the storm moves inland today. The National Hurricane Center noted that the center of Tropical Storm Ingrid was located just inland near latitude 23.8 north and longitude 97.8 west, directly over La Pesca, Mexico. Ingrid was moving toward the west-northwest near 10 mph/17 kph and a turn to the west then west-southwest.

The heavy rainfall rates that TRMM observed is the main threat from Ingrid, especially as the storm moves inland over the mountainous areas. The National Hurricane Center noted that Ingrid is expected to produce 10 to 15 inches of rain over a large part of eastern Mexico with isolated amounts of 25 inches possible.

Ingrid will continue to move inland over Mexico and is expected to weaken as it moves over mountainous terrain over the next couple of days. Some of the mountains in the Sierra Madre Oriental range are over 10,000 feet high. The range spans 620 miles/1,000 kilometers. The Sierra Madre Oriental Mountains extend from the Rio Grande, Texas through the Mexican states of Nuevo León, southwest Tamaulipas, San Luis Potosí, Querétaro, and Hidalgo to northern Puebla. Heavy rains in the mountains are likely to cause flash floods and mudslides.
