Residents of Mexico City and Guadalajara better get their raincoats out this Wednesday. 

According to the National Weather Service (SMN), heavy-to-intense rains and a chance of scattered showers and thunderstorms are expected in both cities. Regions of Jalisco, Colima and Michoacán also will see heavy rains. 

Mexico City will see cloudy skies during the day, with a maximum temperature of 27 C (80 F) before showers and thunderstorms approach the area in the afternoon or evening. 

At nightfall, the temperature will drop to 19 C (66 F) and continue to drop until it reaches 14 C (57 F), by dawn Thursday morning. 

Guadalajara and the rest of Jalisco, Colima and Michoacán can expect a maximum temperature of 30–32 C (86–89 F) and a minimum of 18 C (64-68 F), with cloudy skies. 

Heavy rains are forecast in central Jalisco while scattered showers are forecast for the rest of the state and neighboring Nayarit. 

The SNM has also warned of potential flooding. Heavy rains may be accompanied by lightning and hail and could cause landslides and flooding in low-lying areas. Dust storms may also occur in Jalisco. 

Fog banks are expected in the north and center of Michoacán, leading to reduced visibility on highways. 

Weather conditions in Guadalajara may be caused by a cyclone formation in the Pacific Ocean, 1,250 km southwest of Playa Pérula. This is caused by a low-pressure zone south of Baja California Sur and could lead to the formation of Cyclone Dora — the fourth named storm of the 2023 season in the Mexican Pacific. 

The cyclone poses no danger to the rest of Mexico, according to the SMN.
