Tropical Storm Sonia weakened to a tropical depression early Monday morning and has weakened further as Sonia hit mainland Mexico, the National Hurricane Center reported.

In its 10 a.m. EST update of Sonia, the NHC said the remnants of the storm are here, or 80 miles northeast of Culiacan, Mexico. The former tropical storm has maximum sustained winds of 25 mph and is moving north-northeast at 14 mph.

“Satellite images and surface observations indicate that the circulation of Sonia has dissipated,” the Miami-based NHC said in its 48-hour outlook of Sonia. “Remnant moisture from Sonia will move northeastward across northeastern Mexico and into Texas [Monday.]”

There are no coastal watches or warning in effect due to Sonia.

“Rainfall over Mexico associated with Sonia will continue to diminish [Monday] afternoon,” the NHC said.

The center said it will no longer be issuing advisories on Sonia.
