Some interesting cyclonic events are taking place in the northern tropics on this Friday 28 July 2017.
A set of twin tropical cyclones, HILARY and IRWIN (See our posting of 25 July), appear to be in a collision course midway between Mexico and Hawaii in the Pacific. Now downgraded to tropical storm strength Hilary is moving WNW while nearby to its southwest Irwin is tracking NNW putting these tropical cyclones on a course for potential interaction over the next day or so. Both Hilary and Irwin are packing maximum sustained winds of 110-115 kph posing no threat to land.
Farther to the west, over the Philippines sea a strengthening Typhoon NESAT is starting to brush past the Northern Philippines as it aims for Taiwan. At the same time, Typhoon NORU is over the northwestern Pacific making a turn toward the NNW to the east of Japan. So, this makes for four active named-tropical cyclones over the northern Pacific basin, in addition to several areas of disturbed weather and tropical waves throughout the basin that may be seeds for further cyclonic activity in coming days.
Of interest to us here in South Florida, and to others throughout the Caribbean, Central America, the Gulf and the Atlantic seaboard of the U.S.A., is a tropical wave located approximately 1000 kilometers southwest of the Cape Verde Islands that has been designated as INVEST 97L by NOAA’s National Hurricane Center while monitoring it for possible cyclonic development over coming days.
Farther to the east over waters of the Eastern Atlantic and Equatorial Africa there is a train of tropical waves, including one rather large and strong storm, moving westward toward Hurricane Alley. There is plenty of seeds that may fuel cyclogenesis in that region over the next few days. All interests in our neck-of-the-woods will do well to pay attention, remain alert, and be prepared! MITIGATE!
Just as forecast in our previous posting, the storm at the western end of Hurricane Alley is now a tropical cyclone named Tropical Storm BRET, which makes the 2017 Atlantic Hurricane Season officially open, that is if you are willing to consider Tropical Storm ARLENE (April 2017) and ‘off-season’ tropical cyclone in the Atlantic.
Tropical Storm BRET appears to be headed for Trinidad as it skirts the coast of Venezuela and the southeastern Caribbean beyond where the environment will not favor further development of this system.
Farther west and north in the central Gulf of Mexico the other storm we’ve been watching continues to strengthen and appears of the brink of becoming a tropical cyclones as it moves northward toward Louisiana, Mississippi, Alabama and the Florida Panhandle.
Meanwhile in the eastern Atlantic. tropical waves continue to emerge from the assembly line over equatorial Africa. There appears to be plenty of ‘fuel’ for potential cyclonic activity in coming days. Get ready. Remain alert. Be prepared. MITIGATE!
