Cyclone Yaku: what effects and consequences can it leave in Peru and Ecuador after its presence in the South Pacific

Torrential rains in the north of our country, together with a series of events such as hailstorms, snowfall, warming of sea waters, increased river flow, among other climate changes, are due to ‘water click’an unorganized phenomenon with tropical characteristics, as reported by the National Hydrology and Meteorology Service (Senamhi).

“He National Service of Meteorology and Hydrology of Peru (Senamhi) informs that, off the northern and central coast of Peru, there is an “unusual cyclone with unorganized tropical characteristics”. This clockwise low-pressure system is associated with the warming of the sea surface temperature and the second band of the Intertropical Convergence Zone (ITCZ)”, maintains the institution, indicating that ‘your’ influences extreme precipitation in Tumbes, Piura and Lambayeque.

He added that it is expected that “in the next few days it will contribute to the intensification of the rains in Libertad, Lima and Áncash; particularly in the middle basins of the Pacific slope, generating an increase in flows and an activation of rivers”.

He Cyclone Yaku It formed at the end of February on the Peruvian coast and to this day the institution continues to monitor this system and its course.

In meteorology, cyclone Usually, it generally refers to intense winds accompanied by storms, although it also refers to areas of the planet in which the atmospheric pressure is low. In this second sense, the sense of cyclone is equivalent to that of storm, and It is the opposite phenomenon of the anticyclone.

To Cyclones are usually associated with very intense rains, which can cause widespread flooding. They are also associated with damaging or destructive winds and in the most intense systems, surface winds can reach speeds of over 300 km/h. The combination of wind-driven waves and the low pressure of a tropical cyclone can produce a coastal storm surge – a huge volume of water driven ashore at high speed and with immense force that can carry structures on its way. passage and cause significant damage to the coastal environment.

However, in Abraham Levy’s experiment, the Cyclone Yaku It would be the first to appear off the coast of Peru. “When the sea or the ocean in general reaches temperatures of 27 or 28 degrees It produces these massive storms, they are typical of tropical waters and off the coast of Peru, the occurrence occurs due to coastal El Niño or El Niño or significant warming of the sea”.

“The conditions we are experiencing today in the north are typical of El Niño, the sea is very warm and this is producing the precipitation we have seen over the past 24 and 48 hours,” Levy said.

Likewise, he indicated that “since these warm waters reached the coast itself threat of heavy rains in the most vulnerable areas of Peru, which are the region of Tumbes, Piura and the province of Lambayeque. In Ferreñafe and Chiclayo a little less intensity and when moving south it decreases.

Fearing that Cyclone Yaku could trigger a tropical storm or hurricane, Levy ruled it out altogether. “There won’t be a hurricane, we’re not going to have that. Conditions are likely for storms through March 16.

In the latest report from the Senamhi, between Thursday 9 and Saturday 11 March, there will be precipitation (snow, hail, sleet and rain) of moderate to extreme intensity on the north coast and the sierra. These precipitations will be accompanied by electric shocks and gusts of wind with speeds close to 35 km/h. In addition, the appearance of localized hail is expected in areas above 2,800 m altitude and isolated snow in localities above 4,000 m altitude moderate to extreme are expected in Piura, Tumbes, Lambayeque and La Libertad and light to moderate rains on the central coast.

For him Friday, March 10, Cumulative rainfall is expected with values ​​above 45 mm/day in the northern sierra, above 20 mm/day in the central sierra and values ​​close to 15 mm/day in the southern sierra. In addition, records of more than 50 mm/day are expected in Tumbes and on the Piura coast and 25 mm/day in Lambayeque and La Libertad.

He Saturday March 11Cumulative precipitation is expected with values ​​close to 45 mm/day in the northern sierra, around 20 mm/day in the central sierra and values ​​above 15 mm/day in the southern sierra. In addition, records of more than 40 mm/day are expected on the Piura coast and 25 mm/day in Lambayeque and La Libertad.

In Peru, the Senamhi, COEN and the Directorate of Hydrography and Navigation of the Navy, reported that “an unusual low pressure system is present (cyclone with undefined tropical characteristics). This low pressure system has developed due to abnormal sea surface temperature warming, weakening and movement towards the southwest of the South Pacific High and the second band of the Intertropical Convergence Zone (ITCZ).

during this time at Ecuador the National Institute of Meteorology and Hydrology (Inamhi), the heavy rains on the central and southern coast of the country are due to the influence of the cyclone ‘Yaku’ which is located off the coast of Peru. “The presence of the low pressure system will influence the persistence of heavy rains in different sectors of the central and southern coast of the coastal region of Ecuador in the coming days”

Precisely, in Guayaquil, the intense rains also affected homes, bridges and flooded various streets of the Ecuadorian capital.

From March 9 to 15 the distribution of the rains will be:

IN THE MOUNTAINS, Precipitation (rain, sleet, hail and snow) is forecast, accompanied by electrical discharges and strong to extreme gusts of wind in the northern sierra and the western slopes of the central sierra; similarly, moderate to heavy rains are expected in the southern part of the sierra.

IN THE JUNGLE, Moderate to heavy rains are expected accompanied by electric shocks and gusty winds, with heavier accumulations mainly in the high central jungle and the southern jungle.

ON THE COAST, Heavy rain is expected in the north, while light to moderate rain is expected on the central and southern coast.

They are characteristic of having a strong zone of low pressure on the surface and high pressure in the upper levels of the atmosphere. They come from the formation of centers of low atmospheric pressure in the sea.

The National Center for Disaster Reduction (Cenapred) explains in the Tropical Cyclones poster that this phenomenon forms when a mass of warm, humid air with strong winds swirls around a central area.

“They form in the sea, when the temperature is above 26 degrees Celsius,” he explains according to information from Milenio.
