In addition, Rosly will cause waves of up to 150 kilometers per hour and waves of five to seven meters in Jalisco. It will also wreak havoc on the coasts of Colima and Nayarit, where waves of up to 100 kilometers per hour and waves of three to five meters are expected; in Michoacán the winds will be up to 70 kilometers per hour, and the waves from two to four meters high.

Conagua warns that among the risks are the overflow of rivers and streams, overflows, and landslides.

SUSTAINED WINDS SPEEDS FOR ONE MINUTEABSTRACT
CATEGORY 1119-153km/hDangerous winds will cause some damage. People, livestock, and pets can be injured or killed by flying debris.
CATEGORY 2154-177km/hExtremely dangerous winds will cause extensive damage. In addition to the above risk, mobile homes have a high risk of being destroyed.
CATEGORY 3178-209km/hDevastating damage can occur. In addition to the above risks, almost all mobile homes will be destroyed and there will be a high percentage of damage to buildings.
CATEGORY 4210-249km/hCatastrophic damage will occur. In addition to the above risks, most windows of tall buildings will be blown out, resulting in glass falling, so the threat extends for days or weeks.
CATEGORY 5More than 249km/hCatastrophic damage will occur. A large amount of thrown debris is expected to fly through the air and become dangerous projectiles. Blackouts can last for weeks or months.

Hurricane Orlene made landfall Oct. 3 a little farther north in roughly the same region, about 45 miles (75 kilometers) southeast of the resort of Mazatlan.
