Mayor Daniel Reyes kept municipal classes suspended while a red alert for landslides and aluvión risk stayed in force. He also asked the state for lasting protection works.
La Florida flooding kept municipal classes suspended on Wednesday, 21 October, after the Santiago district stayed under a national red alert. Radio Agricultura and Meganoticias report that the municipality closed 26 schools and its kindergartens.
It matters to foreigners because La Florida, home to many families, sits under the Andes foothills. Mudflows called aluviones can strike there within minutes, so residents are told to avoid ravines.
Classes Suspended After a Red Alert
The Municipality of La Florida announced on the night of Tuesday, 20 October, that it would keep municipal classes suspended on Wednesday. Radio Agricultura reports that the measure covers municipal schools and kindergartens.
Mayor Daniel Reyes, an independent, said the district “is still on red alert”. He expected a second, very intense pulse of rain, as translated from Meganoticias.
“We want to call on the ministry to rethink this measure,” Reyes said, as quoted by Meganoticias. “We are in an absolutely exceptional situation.”
The Education Ministry said on Tuesday that classes restart on Wednesday in five regions, except where schools cannot open, La Tercera reports. Puente Alto and other districts also kept municipal classes suspended.
Which Schools Are Affected
The list published by Meganoticias and Radio Agricultura has 26 establishments run by the municipal education corporation. It covers only municipal schools, and the municipality says it cannot order private schools to close.
Named schools include Escuela de Párvulos Samorito, Colegio Capitán Pastene, Colegio Lo Cañas, Colegio Sótero del Río and Liceo Andrés Bello. The list also names Liceo Alto Cordillera, Liceo Indira Gandhi, Colegio Santa Irene and Liceo Bicentenario de Excelencia Benjamín Vicuña Mackenna.
Reyes urged private and subsidised private schools to consider suspending classes, Radio Agricultura reports. School meals stay available to pupils who need them.
What the Weather Service and Senapred Say
Senapred, Chile’s national disaster prevention and response service, declared a red alert for landslides on Sunday, 18 October. It covers 10 Santiago districts, including La Florida, and stays in force until conditions allow a change, Meganoticias reports.
The national weather service DMC warned of moderate to heavy rain in a short period for Tuesday, 20 October. A DMC forecaster told Emol that foothill areas could get 25 to 35 millimetres, with bursts of 10 to 15 an hour.
The geology service Sernageomin rated the chance of aluviones in the foothills as high, Meganoticias reports. The municipality kept its teams deployed through the night to respond to possible emergencies, Radio Agricultura reports.
Aluvión Risk After Las Condes
An aluvión is a fast mudflow of water, rock and vegetation that runs down a dry ravine after short, heavy rain. One struck eastern Las Condes on Thursday, 8 October, after about 15 millimetres of rain in an extremely short period, Emol reports.
Senapred counted 384 people affected, 56 homes destroyed and no deaths or missing, 24horas reports. Six people were injured, according to Emol.
Reyes told La Tercera that Quebrada de Macul has seven large settling basins built after the aluvión of 3 May 1993. He said the risk there is “much more limited”, but Santa Sofía de Lo Cañas has no comparable works.
Reyes told La Tercera that the foothill sector of Santa Sofía de Lo Cañas is where evacuating people could be needed. The explainer on why La Florida is at risk covers the geography in detail.
Mayor Reyes on a State Response
Reyes told La Tercera on Wednesday the district needs “a response at state level, beyond the government of the day”. He said investments are missing “probably in 30 years, in decades”.
He said weather radars make little sense without mitigation works, and that no single municipality in Chile could carry such works alone. La Tercera reports that he has raised the need with governments from Sebastián Piñera to José Antonio Kast.
The municipality has trucks, heavy machinery and 600 staff deployed, with monitoring around the clock. Foothill access was banned on Sunday, and a camp on the Macul ravine was cleared in February, La Tercera reports.
What It Means for US Readers
Americans living in or visiting eastern Santiago should avoid the foothills, ravines and river banks while the alert lasts. Senapred sends emergency text alerts to phones, and the national mobile alert system is the quickest warning.
No source reviewed reports damage to airports, mines or ports from this episode. Related reading covers the seven-region climate emergency, its legal powers, the Chile explained guide and Rio Times Chile coverage.
What Is Not Known
The municipality has not said whether classes resume on Thursday, 22 October. The municipal website could not be opened, so its position comes from Radio Agricultura, Meganoticias and La Tercera.
La Tercera cites up to 75 millimetres for foothill districts, while the weather service warning cited by Emol said 25 to 35. How much rain La Florida received on Tuesday is unclear.
No official count of flooded streets, damaged homes or injuries in La Florida had been published in the sources reviewed. Meganoticias carried a short video of flooded streets, but its detail was not available for this report.
What Comes Next
Senapred and the weather service will update alerts as the second rain pulse passes overnight. A change to the red alert would follow their technical review, and the municipality says it will use official channels.
A suspension does not mean an aluvión has occurred in La Florida. It is a precaution while the alert remains in force.
