Hurricane Roslyn is already category 4 and is about to hit Mexico: here’s what you need to know


In less than 12 hours, Hurricane Roslyn advanced from category 1 to category 4. That means that, according to the Saffir-Simpson scale, Roslyn now has the potential for ” catastrophic damage ” and that there is “a high risk of personal injury and death ” due to debris and falling objects. 

Roslyn is, with a cutoff at noon on October 22, 240 kilometers from Manzanillo, Colima, and 275 kilometers south-southwest of Cabo Corrientes. Conagua is projected to make landfall on Sunday, October 23. It will produce extraordinary rains in Jalisco, torrential in Colima and Nayarit, and intense in Michoacán.

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.

Hurricane season began on May 15. All of them are classified according to the Saffir Simpson wind scale. Broadly speaking, the scale is as follows:

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.
