As Central America braces itself for the whims of Mother Nature, the region finds itself caught in the chilly embrace of Cold Front 19. Unlike its predecessor, which unleashed a watery fury resulting in at least 15 flooding incidents across Sarapiquí, Limón, Guácimo, and other Caribbean locales, this cold front skates across the territory with a lighter touch, albeit with its own frosty flair.
A Breeze of Change
Gabriela Chinchilla from the National Meteorological Institute (IMN) notes that while the current cold front’s effects are milder compared to its dramatic forerunner, it still packs a punch with moderate to strong winds sweeping across the country’s center and northern regions, day and night, and whistling through every mountain range.
As we wrap ourselves in extra layers, the gusts, ranging between 40 and 70 km/h in the Central Valley and the lower parts of the North Pacific, crescendo to a howling 70 to 90 km/h in Guanacaste and the mountain ranges, with La Cruz witnessing winds that might as well have a speed ticket issued at 95 km/h.
A Sprinkle and a Splash
The cold front also brings with it a pattern of light rain across the Caribbean mountains and the northern zone, with the possibility of nocturnal drizzles dusting the mountainous sectors to the east and north of the Central Valley. Meanwhile, the rest of the country looks to stay dry, perhaps missing out on the atmospheric drama.
Tres Ríos in La Unión reported a shivering 8.4°C, while the urban heart of San José at Barrio Aranjuez warmed up to a slightly toastier 15.2°C, and Limón balanced the scales at a balmy 20.9°C.
The Aftermath and Beyond
As Cold Front 19 prepares to bid adieu to our lands on Tuesday night, it leaves behind not just a trail of brisk memories but also the promise of continued alisio winds. These winds, driven by a high-pressure system lurking in the North Atlantic, will keep the gusty atmosphere alive across the northern Central Valley and Guanacaste for much of the week.
In contrast, the lower Central Valley and the Pacific can look forward to clear skies and warmer days, a signature of this time of the year.
A Season of Chills
This season has seen an unusually high number of cold fronts, 19 to be exact, attributed to the whims of the Arctic Oscillation and the North Atlantic Oscillation, which have favored the intrusion of these chilly visitors. According to Karina Hernández, coordinator of Climatology at the IMN, this influx has been a boon for the agricultural sectors of San Carlos, Cartago, Limón, Upala, and other fertile regions, bringing much-needed rain to their fields.
Moreover, the light rains from this latest cold front have even graced the regions of Oreamuno, Turrialba, and Alvarado in Cartago, contributing to the recharge of some rivers in the Caribbean and the northern zone. This comes as a welcome respite from the unusual warming of the Atlantic waters and the prolonged drought induced by El Niño, which have put a strain on the Pacific region since mid-last year.
As Cold Front 19 glides across Central America and the Caribbean, it weaves a tale of gusts, chills, and a sprinkle of rain, reminding us of nature’s ability to stir up the atmosphere, for better or for worse.
