The "tiny" Hurricane Carlos remained off the coast of Mexico, according to the latest advisory by the National Hurricane Center. Carlos, which is about 85 miles south-southwest of Manzanillo, Mexico, was traveling northwest at 5mph.

According to the hurricane centre, a hurricane watch is in effect for Punta San Telmo to Playa Perula, Mexico. There is also a tropical storm warning for Punta San Telmo to Cabo Corrientes, Mexico.

Carlos is expected to continue moving towards the northwest through Wednesday (17 June) night and then move north-northwest on Thursday. The National Hurricane Center said the hurricane is expected to remain just offshore over the next few days, but a slight deviation to the northeast could bring Carlos closer to the coast.

Maximum sustained winds for Carlos are at 85mph, with some weakening expected in the next 48 hours.

The Category 1 hurricane is forecast to bring heavy rains to the Mexican states of Guerrero, Michoacan, Colima, Jalisco, Nayarit, Durango and Sinaloa, the hurricane centre said. Those states could see between 3 to 6 inches of rain, with isolated maximum amounts of 10 inches.

The rain Carlos produces may lead to life-threatening flash floods and mud slides, the hurricane centre warned.

According to the Associated Press, authorities had to close the waters off Puerto Vallarta to small boats. Cruise ship Carnival Miracle also called off a port call planned for Puerto Vallarta on 17 June, port official Odilon Garcia Castillon told reporters.

The AP reported that Jalisco state education authorities announced that schools in a half dozen towns would be closed.
