The 1842 Mexico hurricane is the first known occurance of a tropical cyclone trasversing from the Atlantic to Pacific or vise versa. As the event was so unexpected, as these often were back in those days, it led to an enormous death toll, estimated to be 2770 by modern sources. The cyclone travelled through the straights of Tehauntepec, before emerging into the Gulf of Mexico and dissipating as a tropical cyclone the next day. Modern estimates put the intensity at 125 mph, with gusts of 155 mph in elevated regions, the best estimate of the cyclones intensity to date.
