Dolly weakened into a tropical depression over northeastern Mexico on Wednesday after moving ashore but another storm threatened to grow into a hurricane off the Pacific coast, forecasters said.
Several schools closed in the northeast and nearly 200 people spent the night in shelters before Dolly made landfall late Tuesday as a tropical storm between the states of Tamaulipas and Veracruz.
But national civil protection coordinator Luis Felipe Puente said the storm had not caused any victims or material damage.
The National Weather Service said Dolly was moving west over the northern state of San Luis Potosi with sustained winds of 55 kilometers (35 miles) per hour.
On the west coast, Tropical Storm Norbert was expected to mushroom into a hurricane later Wednesday as it swirled 385 kilometers (240 miles) south-southeast from the southern tip of Baja California peninsula, according to the US National Hurricane Center.
Norbert packed maximum sustained winds of 100 kilometers (65 miles) per hour while moving northwest at 15 kilometers per hour.
Last year, Mexico was simultaneously struck by a pair of hurricanes, Ingrid and Manuel, on both coasts, killing 157 people, destroying bridges and burying most of a mountain village in the Pacific coast state of Guerrero.
