due to strong winds
caused by new Cold Surge By the A.M. Costa Rica staff The National Emergency Commission announced a Green Alert due to strong gusts of winds, caused by the 13th Cold Surge of the year, expected to continue to affect the country until Saturday. The Cold Surges, CSs, have been traversing the country since Thursday. They are largely controlled by the Surface Air Temperature, SAT, distribution at high latitudes and thermal advection in the lower troposphere. The Green Alert is given when it is anticipated that a meteorological phenomenon endangers a specific area in the country. The authorities activate the community's emergency commissions to take action due to the danger related to the alert. The new Cold Surge entered the country through the North Coast of the Caribbean Sea, so the Green Alert is declared for the areas of the Caribbean Coast (Limón Province), the northern zone of Alajuela Province, the North Pacific Coast (Guanacaste Province) and the Central Pacific zone (Puntarenas and San José provinces). The alert does not apply to the South Pacific Coast where the wind speed is expected to be moderate. The weather report from the Meteorological Institute estimates that the most impacted region of the Cold Surge is in the Caribbean Coast, with the possibility of strong gusts and the dragging of humidity from the Caribbean Sea which has caused moderate rains with amounts between 2 to 15 millimeters. Wind gusts are expected to affect the Central Valley (including cities surrounding San José such as Alajuela, Heredia and Cartago), with amounts between 40 to 60 kilometers per hour. Pay special attention to the northern zone of Guanacaste, specifically in La Cruz Canton, where gusts have reached 101 kilometers per hour. In the rest of the province, there could be gusts with speeds between 80 to 110 kilometers per hour.  Specialists provide the following advice due to the strong gusts: • Be cautious of wind gusts and its possible damage on roofs, electrical wiring, trees and high buildings. • For air travel, expect increased turbulence, as well as in maritime navigation due to increased rough seas, especially in the North Pacific Coast, the Central Pacific Coast and Caribbean Coast. • Stay informed about the alerts issued by the authorities. A.M. Costa Rica urges readers to share this alert with their contacts. -------------------------- What have you heard about emergencies due to strong gusts of wind in your community?
