Weather geeks in the U.S. have been chattering a bit about recent dramatic changes that may signal the beginning of El Niño conditions. One of the more hyperbolic can be found here: washingtonpost.com/blogs/… . NOAA currently sets the probability of some kind of El Niño situation (weak, moderate, strong) by summer/fall at 50%--up from the more routine odds of 33%. So certainly nowhere near a sure thing. But if you're considering travel this summer or fall, you might want to check in on NOAA official El Niño page every month or so: …noaa.gov/products/…churchill.php .
About a year ago, Heather wrote a brief post about her experience with the strong 1997-98 El Niño event in the archipelago: tripadvisor.com/…47399237 (#3).
