This is the best summary I could come up with:

The Mexican National Water Commission and mayor announced the moves at a news conference, but officials did not report the cuts on social media until just four hours before they took effect.

Twelve boroughs, mostly in the west of the city, can expect lower water pressure until the restrictions lift, officials said.

Officials did not specify when that would be, saying only that restrictions would stand for “the next few months.” They noted the rainy season — which at normal levels of precipitation would replenish the city’s water — won’t start until around May.

Officials said El Niño and heat waves caused the recent falloff in rain, but added that drought conditions have been intensifying the past four years and gradually lowering reservoir levels.

Studies have shown climate change creates stronger El Niño patterns that bring periods of decreased rain.

“The country has been subjected to extreme weather phenomena, and the Cutzamala System is no exception,” said the water commission’s head, Germán Arturo Martínez Santoyo.
