TS Isaac forms in At­lantic

South Florida Sun-Sentinel (Sunday) - - Front Page - By Anne Geg­gis and Juan Ortega South Florida Sun Sen­tinel

And Isaac makes three — adding to Trop­i­cal Storm He­lene and a strength­en­ing Florence.

A pow­er­ful hur­ri­cane could strike part of the U.S. East Coast in the com­ing days as Trop­i­cal Storm Florence kept strength­en­ing Satur­day in the At­lantic.

Florence is most likely to hit the south­east U.S., pos­si­bly the Caroli­nas, the lat­est mod­els show. It was about 1,500 miles east of Florida and its path re­mained un­clear five days out from ex­pected land­fall.

The storm, which al­ready was the first ma­jor hur­ri­cane of the 2018 At­lantic sea­son, had weak­ened, but was ex­pected to again be­come a hur­ri­cane by early to­day.

“Florence is fore­cast to be a dan­ger­ous ma­jor hur­ri­cane near the south­east U.S. coast by late next week, and the risk of di­rect im­pacts con­tin­ues to in­crease,” the Na­tional Hur­ri­cane Cen­ter said Satur­day.

Two other trop­i­cal storms, Isaac and He­lene, also are spin­ning in the At­lantic and could be­come hur­ri­canes in the next few days, though none posed an im­me­di­ate threat to Florida.

Bryan Nor­cross, a me­te­o­rol­o­gist with WPLG-Ch. 10, likened the three storms’ tra­jec­to­ries to a pool-ball break, where all are ex­pected to spin off in dif­fer­ent direc­tions.

While Florence could hit land north of Florida, He­lene likely will present no threat to land as it goes north, said Nor­cross, who talked South Florida through Hur­ri­cane An­drew’s pound­ing on tele­vi­sion 46 years ago.

And Isaac, well, that’s any­one’s guess.

“Isaac is just too far away” to pre­dict, he said.

To have this many storms si­mul­ta­ne­ously in the At­lantic is not at all un­usual for this time of year, me­te­o­rol­o­gists say. Septem­ber is the peak month for trop­i­cal weather — and Sept. 10 is the sta­tis­ti­cal peak day, said Den­nis Felt­gen, a me­te­o­rol­o­gist and spokesman for the Na­tional Hur­ri­cane Cen­ter.Here’s a look at the storms:

Florence’s max­i­mum sus­tained winds kicked up a notch — to 70 mph — and kept up a west­ward move­ment at 5 mph. A Cat­e­gory 1 hur­ri­cane has winds of 74 to 95 mph.

The cen­ter of Florence will move over the south­west­ern At­lantic Ocean be­tween Ber­muda and the Ba­hamas on Tues­day and Wed­nes­day, and ap­proach the south­east­ern U.S. coast on Thurs­day.

Trop­i­cal Storm He­lene, about 3,800 miles east of Florida, is strength­en­ing. He­lene has max­i­mum sus­tained winds of 65 mph and is mov­ing to the west at 13 mph, kick­ing up its speed in the last few hours, as of the lat­est hur­ri­cane cen­ter ad­vi­sory.

Fore­cast­ers ex­pected the storm to bring trop­i­cal storm con­di­tions to parts of the Cabo Verde Is­lands on Satur­day night. Of­fi­cials say heavy rain­fall on the is­lands could pro­duce lifethreat­en­ing flash floods. He­lene is pre­dicted to miss the U.S. main­land.

A trop­i­cal de­pres­sion that was up­graded to Trop­i­cal Storm Isaac on Satur­day is headed to­ward the Caribbean and brings a chance of curv­ing north to­ward Puerto Rico and the U.S. main­land, po­ten­tially as a hur­ri­cane.

Isaac is ex­pected to turn into a hur­ri­cane by Mon­day, ac­cord­ing to Na­tional Hur­ri­cane Cen­ter. The storm has max­i­mum sus­tained winds of 40 mph and is mov­ing west about 7 mph, ac­cord­ing to a 5 p.m. ad­vi­sory. Isaac is es­ti­mated to be 2,900 miles east of Florida.

In ad­di­tion to the three trop­i­cal storms, there also is a large area of dis­or­ga­nized show­ers and thun­der­storms south­west of Ber­muda. It has only a 10 per­cent chance of form­ing into a trop­i­cal storm.
