Hurricane Lee has grabbed the eye of forecasters and social media this week because the quickly intensifying storm strikes west throughout the open waters of the Atlantic.
It’s straightforward to have a look at a map displaying a significant hurricane with a forecast path pointed straight at the US and assume the East Coast is in for it. However as of Thursday night time, that situation was not probably the most possible consequence. Even when it was, Lee wouldn’t arrive till late subsequent week, which is past the official forecast from the specialists on the Nationwide Hurricane Heart.
Right here’s what we all know concerning the hurricane:
What’s Lee’s present location and path?
As of 11 p.m. Thursday, Hurricane Lee was about 705 miles east of the northern Leeward Islands, that are within the northeastern Caribbean, and it was shifting west-northwest at 14 miles per hour.

It at present doesn’t threaten any land, and there aren’t any coastal watches or warnings but in impact.
Harmful surf circumstances generated by the storm are prone to have an effect on the Virgin Islands, Puerto Rico, Hispaniola, the Bahamas and Bermuda over the weekend, in line with the Hurricane Heart.
Meteorologists are pretty assured that Lee will keep north of the Caribbean. A number of forecast fashions counsel the storm will veer north, nevertheless it stays unclear if and when that may occur — and whether or not it turns earlier than threatening the US. In a printed forecast dialogue, the middle stated, “It’s approach too quickly to know what degree of impacts, if any, Lee may need alongside the U.S. East Coast, Atlantic Canada, or Bermuda late subsequent week, significantly for the reason that hurricane is anticipated to decelerate significantly over the southwestern Atlantic.”

How large is that this storm going to get?
Lee strengthened from a Class 1 storm to a Class 2 over the course of some hours on Thursday, and jumped to a Class 4 later within the day earlier than strengthening to a Class 5 hurricane by 11 p.m.
The storm can be anticipated to stay a hurricane nicely into subsequent week, and whereas its depth might fluctuate, fashions predict it is going to attain Class 5, in line with the middle.
What are the probabilities it is going to hit the U.S. East Coast?
There may be some likelihood, however it’s at present not the possible consequence. It may also hit Canada or keep farther east and transfer throughout Bermuda.
When will we all know extra?
Clearly, the nearer we get to subsequent week the higher the forecasts will probably be. However by this weekend, forecasters must be getting a greater concept of the forecast path for Lee.
Inform me what the fashions present. (Additionally, what’s a spaghetti mannequin?)
One model of a mannequin final weekend instructed that the East Coast might get hit, a chance that has lingered within the minds of some forecasters and novice climate watchers, partly due to widespread social media hype.
However if you take a look at all of the variations of the mannequin, there’s not an awesome consensus on the place the middle of the hurricane will go after this weekend, with some outliers near the East Coast.
Generally, a number of fashions are displayed on a single map with strains that plot the place that pc simulation believes the middle of the storm will probably be 5, seven and even 14 days sooner or later. Often called spaghetti fashions, these mapped model outputs get their title from their resemblance to lengthy strands of pasta.
The nearer the strains are to 1 one other, the extra confidence it provides forecasters in what the storm may do. For the following few days, there’s a fairly dependable consensus that the storm will monitor northwest.
When the spaghetti strains unfold wider aside, forecasters have many extra prospects to cope with. There may be quite a lot of unfold past this weekend, which is why this storm will probably be essential to regulate. Proper now, all the pieces is on the desk.
What has this 12 months’s hurricane season been like thus far?
We’re a bit over midway by the Atlantic hurricane season, which began on June 1 and runs by Nov. 30.
In late Could, the Nationwide Oceanic and Atmospheric Administration predicted that there can be 12 to 17 named storms this 12 months, a “near-normal” quantity. On Aug. 10, NOAA officers revised their estimate upward, to 14 to 21 storms, and the previous few weeks have been busy.
Lee is the twelfth named storm — thirteenth when you depend an unnamed storm in January that specialists on the Hurricane Heart stated ought to have been named — to kind within the Atlantic. It is usually the seventh since Aug. 20, when two tropical storms, Emily and Franklin, shaped. Per week later noticed the arrival of Tropical Storm Idalia, which made landfall alongside Florida’s Gulf Coast as a Class 3 hurricane on Aug. 30.
There may be strong consensus amongst scientists that hurricanes have gotten extra highly effective due to local weather change. Though there won’t be extra named storms total, the chance of main hurricanes is rising.
Local weather change can be affecting the quantity of rain that storms can produce. In a warming world, the air can maintain extra moisture, which implies a named storm can maintain and produce extra rainfall, like Hurricane Harvey did in Texas in 2017, when some areas acquired greater than 40 inches of rain in lower than 48 hours.
Researchers have additionally discovered that, over the previous few many years, storms have slowed down, sitting over areas for longer.
When a storm slows down over water, the quantity of moisture the storm can soak up will increase. When the storm slows over land, the quantity of rain that falls over a single location will increase; in 2019, for instance, Hurricane Dorian slowed to a crawl over the northwestern Bahamas, leading to a complete rainfall of twenty-two.84 inches in Hope City throughout the storm.
