Hurricane Alley is active in the Atlantic!

Tropical cyclone activity continues in the Pacific Ocean. Today 17 August there are two strong, and strengthening, typhoons GONI and ATSANI in the far northwestern Pacific aiming in the general direction of Taiwan and Southern Japan. This raises  the possibility that a region that has been battered continuously in 2015, as recently as a couple of weeks ago, may be in for another strong impact over the next few days.

Also in the Pacific, but in its eastern confines there is  Tropical depression ELEVEN some 1,000 kilometers west of the peninsula of Baja California in Mexico.

Worthy of notice today as well is strong tropical wave moving westward along Hurricane Alley in the Atlantic, some 1000 kilometers southwest of the Cape Verde Islands, which is showing signs of getting organized and perhaps developing into a tropical cyclone over the next 48 – 72 hours. Could this be the genesis of DANNY, the fourth named storm of the 2015 Atlantic Hurricane Season?

Despite an early start of the 2015 season, the Atlantic basin has remained rather quite under the influence of a strengthening El Niño off the Pacific coast of South America. Today, however, in addition to this tropical wave moving west along Hurricane Alley toward the Lesser Antilles, there is a train of tropical waves over equatorial Africa progressing toward the eastern Atlantic that may be the seeds for future cyclonic activity, just as we approach the historical peak of the annual Atlantic hurricane season.

Only time will tell i we are witnessing the gestation of DANNY over the Atlantic, or if any of the tropical waves riding behind will develop into a tropical cyclone, but in the meantime all interest in the Caribbean, the Gulf, and in Florida will do well to pay attention, remain alert, be prepared, and continue to practice mitigation!

21 July 2014: Tropical Depression TWO & Typhoon Matmo!

Who needs hurricanes and tropical storms when we are having a daily dosage of foul weather, with plenty of rain, lightning and thunderstorms, in South Florida? But do not get used to this daily routine and forget this is still the 2014 Atlantic hurricane season.

Speaking of which, there in the midst of ‘hurricane alley’ there is Tropical Depression TWO moving toward the Windward Islands, while a train of disturbed weather and a couple of tropical waves over Equatorial Africa trail right behind it. So, there is some potential cyclonic activity in our basin. All interests from Barbados to the Virgin Islands should monitor this system closely over the next couple of days as it continues to track generally westward.

On the opposite side of the world, over the far northwestern Pacific, in a region that has already seen several tropical cyclones, including a recent Super-typhoon, there is Typhoon MATMO a large. but not too strong of a system now menacing the northern Philippines, Taiwan and even China and the Korean Peninsula.

Still over the Pacific but farther to the east, all the way to the coast of Mexico and Central America, there is a rather long aggregation of tropical waves and disturbed weather cells reaching all the way to the Philippines Sea and the western Pacific where there two large systems showing some potential for further, even cyclonic development over the next day or so.

Over in the Indian Ocean, it is the northern and northeastern regions of the basin that are displaying rather large areas of stormy weather. This display of stormy weather is seen clearly in satellite images taken with an infrared filter.

In summary, there is enough cyclonic, potentially cyclonic, and just plain stormy and foul weather in the northern tropics around the world, to remind everyone that this is the time of the year when we must remain alert, be prepared and continue to mitigate!
