# 14 IS HERE! A DELUGE IN NICARAGUA!

Some ten days ago, around September 26 or 27, a couple of disturbed weather cells formed in the southeastern Caribbean to the east of Costa Rica and Nicaragua, just as we were monitoring tropical cyclones KIRK and LESLIE in the Atlantic basin.

Although relatively small, these disturbances caught my attention mainly because of their location and a surrounding favorable ocean-atmosphere environment in the Caribbean, the Gulf of Mexico, and the East Pacific waters off Central America. On that basis I tagged  this cells for further monitoring.

Sure enough, these disturbances in the Caribbean congealed into a large stormy weather cell just as a disturbance over the east Pacific also grew. The interaction of these systems generated heavy rains in Panama, Costa Rica, and Nicaragua, and eventually over an entire region from northern Colombia to southern Mexico.

In Nicaragua’s Pacific coast region it has rained daily for the last ten days. In Managua, the capital city, and other areas they have had up to 100 mm (4″) on rain per day for the past 3 – 4 days. Widespread flooding has taken place throughout the country. Civil Defense authorities issued a Red Alert for several municipalities. In some areas the ground was so saturated that water was coming into houses from the ground up through the floor. Reports of heavy damage and at least eight dead are evidence of a potential disaster in the making. Other countries in the region, especially El Salvador and western Honduras have suffered similar impacts.

Collaterally with the deluge over Nicaragua and devastation over the entire region, the tropical disturbance in the Caribbean has continued to grow and get better organized as it  moved generally northward near the coast of Nicaragua, Honduras, and Belize.

Today, Sunday 7 October, this system if off the coast of the state of Quintana Roo, Mexico, in the Yucatan Peninsula, and has been classified as tropical depression #14 of the 2018 Atlantic Hurricane Season. The storm is rather large, generating torrential rain over a wide region of the northwestern Caribbean, and it is showing strong cyclonic tendencies as it progresses toward the Gulf of Mexico where surface water are rather warm at around 30 Celsius.

Given these aspects and the favorable environment around and ahead of the storm, it is highly probable it could become a tropical storm within the next 12 – 24 hours, and entirely possible that it may reach hurricane strength once in the Gulf.

The storm’s current projected track, which takes into account numerous factors over a wide region that will influence it, has the storm starting to turn toward the northeast once it reaches the south-central Gulf. This means Florida is within the projected track and needs to monitor this system closely starting now, especially along the central-northern Gulf coast and the Panhandle.

While the priority now is Tropical Depression #14, we also need to monitor several tropical waves and stormy cells currently moving westward along ‘hurricane alley’ and to the north of Puerto Rico. as well as others over Equatorial Africa.

There is plenty of hurricane season still left in 2018 in the Atlantic basin and elsewhere. Hurricane SERGIO is forecast to turn northeastward toward the Baja California peninsula for a repeat impact on Northwestern Mexico and the Southwestern USA, which were hammered with wind and torrential rain from ROSA just a few days ago.

Remain alert. Be prepared. MITIGATE!

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!
