A total of 20 weather events are forecast for the next Tropical Cyclone Season in the Pacific Ocean, which will begin on the 15th of the current month and end on November 30.
Of these, two are expected to reach the category of tropical depression, 10 that of a tropical storm, five are forecast to reach moderate hurricanes of categories 1 and 2 on the Saffir-Simpson scale, and three more will reach intense hurricanes of category 3 , 4 and 5, according to the forecast prepared by the Secretary of the Navy.
In the Pacific Ocean, cyclones that reach the category of tropical storm and hurricanes are expected to bear the names Andrés, Blanca, Carlos, Dolores, Enrique, Felicia, Guillermo, Hilda, Ignacio, Jimena, Kevin, Linda, Marty, Nora, Olaf, Pamela, Rick, Sandra, Terry, Vivian, Waldo, Xina, York, and Zelda.
While for the Atlantic Ocean the 2021 Tropical Cyclone Season will begin on June 1 and will also conclude on November 30.
There, 18 meteorological phenomena are expected to form, of which five are predicted to reach a tropical depression, eight a tropical storm, four moderate category 1 and 2 hurricanes on the Saffir-Simpson scale, and five could become Intense hurricanes of categories 3, 4 and 5 on the Saffir Simpson scale.
On said coast, the phenomena that reach a tropical storm from now on will be named Ana, Bill, Claudette, Danny, Elsa, Fred, Grace, Henri, Ida, Julián, Kate, Larry, Mindy, NIcholas, Odette, Peter, Rose, Sara, Teresa, Víctor and Wanda.
According to its stage of evolution, a tropical depression is an area of atmospheric instability associated with the existence of an area of low pressure, which favors the incipient generation of convergent winds with eventual organization for the development of a tropical depression, according to with the National Meteorological Service.
In the tropical depression the winds increase on the surface as a result of the existence of a low pressure zone. These winds reach a sustained speed of 62 kilometers per hour.
While in the case of the tropical storm, the continuous increase in winds causes them to reach sustained speeds between 63 and 118 kilometers per hour. The clouds are distributed in a spiral shape.
When the cyclone reaches the intensity of a tropical storm, it is assigned a name pre-established by the World Meteorological Organization.
While the hurricane is a tropical cyclone in which the maximum sustained winds reach over 119 kilometers per hour.
The cloudy area covers an extension between 500 to 900 kilometers in diameter, producing intense rains. The eye of the hurricane normally reaches a diameter that varies between 24 to 40 kilometers, however, it can reach up to about 100 kilometers.
The hurricane is classified on the Saffir-Simpson scale and the speed of its winds is taken as a basis.
The category 1 hurricane has winds of 119 to 153 kilometers per hour, the category 2 has winds of 154 to 177 kilometers per hour, the category 3 has winds of 178 to 208 kilometers per hour, the category 4 hurricane has winds between 209 and 251 kilometers per hour and the category 5 has winds of 252 kilometers per hour or more, according to the SMN.
