Ernesto's Going To Make It!

There is every indication that Tropical Storm Ernesto will be that rarest of storms to actually successfully cross from the Atlantic to the Pacific (across Mexico's Isthmus of Tehuantepec) and after losing Tropical Storm status, to regain it.

I always thought only a very intense hurricane could be strong enough to cross, but apparently a big, sloppy, loosely-organized storm is better-suited for the crossing. The storm system has to be big enough to straddle Mexico to successfully make the transition, and intense hurricanes, paradoxically, are too small.

Crossing fingers!
