Tropical Storm Henri (2009)

Storm Active: October 6-8

Near the end of September, a tropical wave emerged off the coast of Africa and moved westward. By October 1, the system already was associated with a large area of showers and thunderstorms. The deep tropical moisture enriched the system and contributed to its organization, but it did not develop a well-defined center. The wave moved northwest, out of favorable conditions, but convection persisted. Then, on October 6, a rapid intensification occurred, and the system was declared Tropical Storm Henri. Henri's convection was displaced to the east of the center by El Nino-related west to east sheer, much like Danny and Erika before it. Despite these adverse conditions, Henri gained strength, reaching its peak intensity of 50 mph winds and a pressure of 1005 millibars. Henri paralleled the northern islands of the Caribbean Sea to their north, causing raised surf. Henri weakened later on October 7, and, overnight, became a tropical depression. By the early evening of October 8, Henri had disintegrated into almost nothing on satellite imagery, and it decayed into a remnant low. The low quickly dissipated on October 9. No significant effects resulted from this system.

Uh, wow. Ach was right. This is freaking brilliant! (Not that I follow most of this stuff, but the amount you know about weather really is incredible).
Not to get all sappy and stuff, but keep up the good work! :)

Ha Ha. This wasn't even my best post. Not even close. I don't think you'll ever actually get this comment. So, that's about it. Ta-ta. Come to think of it, I actually never say "ta-ta" so goodbye.
