Stagione degli Uragani - 2021

[burian br]

L'ex uragano Larry è prossimo alla Groenlandia, di cui percorrerà la costa orientale!

A Prince Christian Sund, estremità meridionale della Groenlandia, attualmente 970 hPa e vento con raffiche fino a 170 km/h!!

Le previsioni portano fino a 1,5 metri di neve sul lato orientale della Groenlandia! Un articolo che ho trovato sul web titolava "even hurricanes can dare a dream" e un altro "hurricane larry thinks it's a blizzard".

Aggiornamenti dall’Atlantico interessanti questa mattina. Nicholas, attualmente tropical Storm, è prevista viaggiare verso la costa texana dove è stata diramata allerta per tropical Storm e in un tratto potrebbe essere elevata ad allerta per uragano, dipende se passerà da acque più calde deviando leggermente il proprio corso a destra oppure no, al momento è previsto come intensità massima TS.

Sempre per le conseguenze di Nicholas dovrebbero arrivare tante piogge nella zona di Houston, dove c’è una probabilità abbastanza importante di alluvioni lampo, oltre a un’onda di tempesta (storm surge) intorno a 1/2 metri sulla costa texana.

Nel frattempo, l’area a largo delle Azzorre e la prima area che avevamo intorno a Capo Verde non sono previste con sviluppi particolari, ma abbiamo l’area intorno alle Bahamas e una Tropical Wave in partenza dall’Africa a breve verso ovest che al momento hanno buone probabilità di sviluppare una depressione tropicale. Vediamo un po’ come evolvono queste due situazioni interessanti.

Update flash mattutino, Nicholas che nella notte è diventato uragano categoria 1, ha fatto landfall un’ora fa sulla costa texana

14 Sep 2021 - 6:00 UTC ...NICHOLAS MAKES LANDFALL ALONG THE TEXAS COAST... ...HEAVY RAIN, HIGH WINDS AND DANGEROUS SURGE ONGOING... As of 1:00 AM CDT Tue Sep 14 the center of Nicholas was located near 28.8, -95.7 with movement NNE at 10 mph. The minimum central pressure was 991 mb with maximum sustained winds of about 75 mph.
14 Sep 2021 - 3:00 UTC ...NICHOLAS BECOMES A HURRICANE... ...BRINGING HEAVY RAINS, STRONG WINDS, AND STORM SURGES TO PORTIONS OF THE CENTRAL AND UPPER TEXAS COASTS... As of 10:00 PM CDT Mon Sep 13 the center of Nicholas was located near 28.4, -95.8 with movement NNE at 10 mph. The minimum central pressure was 988 mb with maximum sustained winds of about 75 mph.

Mi sembra di vedere una certa stazionarietà tra Texas e Louisiana, il che è un grosso problema per gli accumuli di pioggia

Peter e Rose stanno andandosene senza grosse novità



Occhio invece alla TD numero 20, che potrebbe a breve diventare Sam e poi punterà dritto i Caraibi come categoria >=3 secondo le attuali previsioni

Confermato, Sam si sta spostando verso ovest a circa 15 miglia orarie, e attualmente si trova circa 1300 miglia ad est dei Caraibi orientali

[Matte92]

Sam, che in pochissimo tempo è diventato un uragano cat.1 adesso ha momentaneamente rallentato la sua corsa a diventare più forte, sistema bello organizzato, dal sat si vede benissimo, i modelli prevedono al momento un tragitto molto simile a Larry

In Atlantico periodo agitato, oltre a Sam, un’area a est di Bermuda potrebbe diventare una tempesta tropicale o subtropicale, è una nuova tropical wave è prevista partire a sud di Capo Verde, con ottime potenzialità di creare un nuovo sistema simile a Sam.
Infine i resti di Odette a largo delle Azzorre che i giorni scorsi erano previsti con qualche probabilità di formare qualcosa, probabilmente non riusciranno a formare alcun tipo di sistema

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Hurricane
Sam, located about 1300 miles east-southeast of the northern Leeward
Islands.

1. Surface observations and recent satellite wind data indicate that a
surface low located a couple hundred miles north-northeast of
Bermuda is gradually becoming better defined as it interacts with an
upper-level trough. This system is producing winds of 40 to 45 mph
north of the low center and additional development into a
subtropical or tropical storm appears likely. Advisories could be
initiated as soon as this afternoon as the system moves slowly
toward the north-northwest over the next day or so. Additional
information on this system, including gale warnings, can be found in
High Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...70 percent.

2. A gale-force, non-tropical low pressure system, the remnants of
Odette, is located less than 600 miles west of the
westernmost Azores. Showers and thunderstorms have mostly
dissipated near the low, and strong upper-level winds are now
expected to prevent further development as this system moves
gradually southward until dissipation. Additional information on
this system, including gale warnings, can be found in High Seas
Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.

3. A tropical wave is expected to move off the west coast of Africa by
the end of this weekend. Thereafter, environmental conditions are
forecast to be conducive for gradual development, and a tropical
depression could form by the middle of next week while the system
moves westward at 10 to 15 mph over the far eastern tropical
Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.

Vedo che siamo già alla lettera T, di solito, mediamente, fino a che lettera si arriva?
