CNN reports that Hurricane Patricia has made landfall in Mexico; Patricia is notable for having the third-lowest barometer reading ever recorded, and as "the strongest hurricane ever observed in the eastern Pacific or Atlantic oceans." Slate points out that at one point, "satellite estimates of Patricia’s intensity broke the Dvorak scale, peaking at 8.3 on the 8.0 scale. ... In fact, Patricia is now very close to the theoretical maximum strength for a tropical cyclone on planet Earth." The Weather Channel is tracking the storm's path, and predicts "catastrophic damage ... along a narrow path as the eye slices into the interior of southwest Mexico Friday night." Here's a map from the National Weather Service showing Patricia's track as well as projected path.
