Hurricane Patricia—the category 5 storm with maximum sustained wind speeds of 200 mph near the eye—is expected to make landfall along Mexico’s Pacific coast later this evening.

Earlier today, the U.S. National Hurricane Center advised immediate evacuation for southwestern Mexico’s coastal residents, especially in regions with low elevation, though inland residents are also at risk of “life-threatening flash floods and mudslides.”

Many Reddit users with friends and family members in the hurricane warning area are commenting on the evacuation efforts:

One user relates a frightening scene from their uncle in Puerto Vallarta, who shared that some tourists took surfboards into the water as the storm approached, apparently oblivious to how serious the impact would be:

Translation: “I have an uncle in [Puerto] Vallarta who says that many tourists are in the water with parachutes and surfboards that think that the storm is going to be some small thing, nothing more.”

Hours ago, meteorologist Sean Sublette and Climate Central writers Andrea Thompson and Brian Kahn answered redditors’ questions about the storm in an AMA with the Reddit Science community:

Kahn noted that Patricia is “the fastest strengthening storm ever recorded in the Western Hemisphere.”
