The warning took effect from 9:20 p.m. to 10:35 p.m. on Friday. Prior to its issuance, Meteorological and Geophysical Bureau (SMG) issued the yellow warning at 7:15pm, in expectation of heavy rainfall that may reach or have already reached 20 mm in the past or the next hour.

Under the impact of the downpour, many locations in the city experienced minor to intermediate flooding.

In response to flooding, several tunnels or underpasses were closed under the downpour. Closed channels are located at the Border Gate, Avenida do Dr. Rodrigo Rodrigues, Praça de Ferreira do Amaral and the Main Reservoir, as well as other locations.
The downpour also caused two landslides, both in Coloane. Both incidents blocked public roads but caused no injuries.
