Following back-to-back, major eruptions of the Calbuco volcano in southern Chile, which occurred for the first time in 42 years on April 22, the volcano registered a third eruptive pulse Thursday.
According to CIMAT - EARLY WARNING MONITORING INFORMATION CENTER, Calbuco registered the third pulse of the eruption and forced preventive evacuations in the affected area.
"Unlike eruptions last week, winds above the volcano will not direct the ashes to Buenos Aires or Santiago after the current eruption," AccuWeather.com Meteorologist Jim Andrews said.
"On the contrary, winds lead the ash to the east and southeast of the volcano through Friday morning."
"If the volcano is still spewing ash on Friday night and on the weekend, a change in wind direction could then carry the ashes to Buenos Aires and thus cause flight delays." Andrews added.
According to recent information from the National Geology and Mining (Sernageomin) of Chile, the plume of Calbuco Volcano is low.
Likewise, with respect to weather conditions in the area, AccuWeather.com Expert Meteorologist Kristina Pydynowski said the situation could change as some showers passengers will be presented later Thursday night and shaping a stable band of rain during the first part of Friday.
"Rainfall amounts are about 0.50 of an inch (12 mm) and may be extended until the afternoon," she said.
