Erin its 1,300 km diameter: This article explores the topic in depth.
However,
Erin its 1. For example, 300 km diameter:
Erin, the first hurricane of the Atlantic season, turned into a real atmospheric colossus in a few days. In addition, After a dazzling intensification which propelled it in category 5 On the Saffir-Simpson scale. In addition, it now runs along the east coast of the United States and should even touch, although strongly weakened, northern Europe.
Its center remains several hundred kilometers offshore. Similarly, but its extraordinary size already allows it to raise waves of 3 to 6 meters and project destructive winds up to the coast.
An Atlantic giant
Hurricane generally vary between 500. Furthermore, 800 km in diameter, some rarely reaching 1,000 km. In addition, Erin. For example, even if he is not the largest (this title returned to the Typhon Tip, in 1979, with its 2,200 km) that erin its 1,300 km diameter we recorded, still sprayed this average. Furthermore, Wednesday August 20, NASA satellite images showed that it had extended over 1,300 km, with cloudy strips that bordered by 1,400 km !

Erin went through a period of rapid intensification. Nevertheless, strengthening from a Category 1 to a Category 5 hurricane in around 24 hours.@NASA’s GPM Core Observatory passed over Hurricane Erin at 6:23a.m. Similarly, EDT on August 16th, while it was intensifying. pic.twitter.com/1cjErVekCy

Its dazzling growth has been accompanied of a repetition of his equally spectacular violence : August 16, in less than 24 hours, Erin went from category 1 to category 5 (the maximum on the Saffir-Simpson scale). The NASA GPM Core GPM Observatory has even made it possible to view in 3D the stormy columns reaching. (see tweet erin its 1,300 km diameter above) more than 15 km high during this “start” of intensity.
At the same time. Noaa hurricane hunters penetrated the cyclone eyebringing in mind -blowing images of an almost calm circular space, surrounded by the wall of the eye where the winds and the rains are the most violent.
Today. Erin has weakened in category 2, with sustained winds from 160 to 180 km/h, but its colossal size allows it to influence a immense portion of the ocean. According to the National Hurricane Center (NHC). its storm winds extend up to 425 km from the center: a real atmospheric cover which exhibits the whole Atlantic coast, from southern Florida to Delaware.
American ribs on the front line
If Erin should not touch the land directly (fortunately!), Its effects are already felt. North Carolina has declared the state of emergency. ordered the compulsory evacuation of certain areas of the chain erin its 1,300 km diameter barrier of Outer Banks, particularly vulnerable to floods (see below). Waves of 3 to 6 meters have already swept the coast, destroying several homes built on stilts.
My heart goes out to all the people affected by Hurricane Erin! This home in North Carolina broke free & just started floating away! Last year my family was affected & lost almost everything we had & we’re just coming back from it.These families need all the support they can get. pic.twitter.com/QFlFRmOpdV

The NHC has issued a coastal submersion notice, and tropical storm alerts are currently in force for North Carolina and Virginia. Throughout the Atlantic coast, up to the Jersey Shore, the beaches were closed to swimming. Erin, even, if he is far from the ribs, generates return currents (” rip currents »), as our colleagues report 20 minutes.

The latter are formed when the water accumulated by the waves on the beach seeks to leave outwards. She then rushes into narrow and fast channels, real liquid treadmills capable to snatch the most experienced swimmers offshore. Burning side effects of storms. unfortunately very well known in the United States, equivalent in a way to our baïnes on the French Atlantic coast.
Even if Erin will not have been so destructive that the Hurricane Milton last year, which killed 45 people. From his genesis. when he was still only a tropical wave wavy off West Africa, his thunderstorms caused violent floods In Cape Verde, costing nine inhabitants of L’île de São Vicente.
- Erin quickly formed in the Atlantic, briefly reaching the maximum category with an extraordinary size of more than 1,300 km.
- Although it remains offshore. its powerful winds and its several meters waves are already affecting the erin its 1,300 km diameter American east coast, causing evacuations and beaches closings.
- Before becoming a hurricane, the system had already caused serious floods in Cape Verde, causing nine victims.
