The final storm of the 2013 Pacific Tropical Season would form in November and, like many before it, drift northward into parts of Mexico.
Sonia began its tropical live as a Depression on November 1st about 300 miles to the south/southwest of Manzanillo in Mexico.
It would be poorly organized and take two days to become a Tropical Storm. Even beyond that, Sonia would not gain much strength as it approached the Mexican coast, with peak winds of 45 miles per hour.
It moved inland on November 4th near Culiacan in Mexico and would break up later that day.
That ended the Tropical season in the Pacific for 2013.
