US Tropical "Protection"? (9/7)

The tropics are very busy as of September 7 ... However, little or no threats exist for the US anytime soon! As of September 7-9, hurricane Katia and tropical storm Maria are churning in the open tropical Atlantic, and NOT expected to affect any land. Tropical storm Nate has formed in the Bay of Campeche, and expected to move into Mainland Mexico later this week. As I mentioned, VERY busy Atlantic tropics, but no threat to the USA at this time.



The graphic above shows the general weather pattern during the week of September 7, 2011. Note (in the graphic above) that despite quite a bit of activity in the Atlantic, the combination of a persistent trough off the US East coast as well as weak high-pressure ridging in the southern Gulf of Mexico, the southeastern and eastern US / northern Gulf regions are sort of in a "quiet zone" (blue area) and nestled in between regions of above-normal risk for tropical cyclones (red areas).
