2017 ATLANTIC HURRICANE SEASON IS 43% DONE!

On this Saturday 19 August we are eleven weeks and two days into the 2017 Atlantic Hurricane Season, which means the ‘official’ Atlantic season is now 43.4% complete. Technically this means we have fourteen weeks and five days left in the season, unless Mother Nature decides to do something different.

More important than how much time is left for the official 2017 Atlantic hurricane season to be over, is the fact that we are approaching what historically  has been the peak of the Atlantic season, the first half of September.

The Atlantic has been busy with tropical cyclones so far in 2017, with eight named storms so far; Tropical Storm HARVEY, now in the east-central Caribbean and moving in the general direction of Belize and the Yucatan, is the 8th named tropical cyclone in 2017 in the Atlantic basin.

In what could be a possible sign of things to come during the approaching peak of the season, there are several tropical waves and areas of disturbed weather following behind HARVEY to the northeast of Puerto Rico and along ‘hurricane alley’ all the way to the eastern Atlantic waters off the coast of equatorial Africa south of the Cape Verde Islands, which could be seeds for potential cyclogenesis in the basin. A possible contributing factor to such potential cyclonic activity could be the rather warm surface waters along ‘Hurricane Alley’, in the Caribbean and the Gulf and other areas of the Atlantic basin.

On the other side of the continent, over the eastern waters of the north Pacific, the 2017 hurricane season that officially started on 15 May has also been a busy one so far, with eleven named tropical cyclones in 13 weeks. The latest tropical cyclone there is Tropical Storm KENNETH now moving NNW and away from land.

All interest affected by cyclonic activity generated in the Atlantic basin and in the eastern north Pacific sub-basin must pay attention. Get ready. Be prepared. Remain alert. MITIGATE!
