Flamingos in the men's room

For a while on Wednesday, it looked like Irma might bestow her dire power on Washington, DC. But no housecleaning this time.

In today's post we have 2 cartoons and the image that inspired the title of today's post.

This article by NPR (National Public Radio) is a good read: Flamingos In The Men's Room.

More than 50 Caribbean flamingos take shelter in a men's restroom at the Miami Metrozoo (now Zoo Miami) on Sept. 25, 1998. Zookeepers rounded up the birds to protect them from the effects of Hurricane Georges. This was not the first time the zoo had to corral flamingos in a restroom. They were also in there during Hurricane Andrew, six years earlier.

Patricia and Wilma

Hurricane Patricia, EcoWatch

Early last Friday there was dire news of a category 5 hurricane, named Patricia, that was expected to make landfall in Mexico later in the day. Patricia was reported as the strongest hurricane ever recorded in the western hemisphere. Luckily she struck land in a relatively uninhabited area and her winds had subsided to about 160 miles per hour, as reported by the Washington Post in How Patricia, the strongest hurricane on record, may have miraculously killed so few. Here's a video from GlobalLeak News showing what Patricia and her 160 mph winds looked like.

Patricia vies with hurricane (aka tropical cyclone) Wilma in the statistics department. However, Wilma traveled further and caused a great deal more damage. This was Wilma's path.

What got me to wondering was "what exactly does a change of 100 millibars air pressure mean?" While I wasn't able to find a direct answer (guess you have to be there), I did find info on how high-low pressure works at WeatherWorks.  Here are a couple of diagrams. Note that highs move clockwise and lows, counter-clockwise--at least north of the equator.

With high winds it seems to me the most destructive part is the constant barrage of force prying things apart in small steps.  Here's an example of how Wilma worked, published by Tropmet.
