The hurricane center said Beatriz could dump 8 to 12 inches (200 to 300 millimeters) of rain across Oaxaca, with higher accumulations in spots, likely causing life-threatening flash floods and mudslides.
The agency said Beatriz will move inland early Friday morning.
The rains damaged some infrastructure, with officials identifying 22 sites where highways along coasts, mountains and isthmus sustained damage. A woman and two children were crushed to death by collapsing houses as Tropical Storm Beatriz swept southern Mexico, and one person remains missing, authorities said yesterday.
Beatriz was expected to weaken once it hit land in southwestern Mexico on Thursday evening, the NHC added, and peter out over the mountainous region on Friday.
There can be localized flooding in the states of Chiapas, Tabasco and Veracruz as downpours from the depression spread northward.
A 214-meter-long bridge over the Tequisistlan River is also in need of fix, following the rains.
