But the National Hurricane Center expects this troubled weather zone to become a tropical storm in Isaiah before reaching Puerto Rico and the Leeward Islands from Wednesday through Thursday. The main impact in these areas will be gusty winds and heavy rain as the system continues to improve.
Starting Tuesday morning, the National Hurricane Center has begun providing advice on the emerging system as it has amassed strength. Air Force Reserve Hurricane Hunter’s mission to the unrest is scheduled for Tuesday afternoon.
Tropical storm warnings are for Puerto Rico, including Vieques and Culebra, as well as the U.S. Virgin Islands. Antigua, Barbuda, British Virgin Islands, Guadeloupe, Martinique and St. Maarten is also warned of tropical storms. In the northern Leeward Islands, Puerto Rico, and surrounding areas, heavy rainfall of 3 to 6 inches in length and local rainfall of 10 inches are possible, the NHC warns, providing a possible flood.
The name Isaias is a Spanish version of the biblical name Isaiah and is pronounced “ees-ah-EE-ahs”.
If he is named as expected, he will cancel the early “I” storm that Irena currently has, named more than a week later, in 2005. August 7, Record.
Finally, the system could affect southeastern Lower 48 states, particularly at risk in Florida.
The earliest recorded storms C, E, F, G and H were also shown this season – Cristobal, Edouard, Fay, Gonzalo and Hanna.
Hurricane season forecasts predicted that in 2020. It will reach an unusually active hurricane season when the chances of the U.S. coast are higher than average. The extremely warm ocean surface temperatures in the tropical Atlantic, including the east coast and the Gulf of Mexico, will increase the threat, exacerbating the potential intensity of the resulting cyclones.
Observe the storm
On Tuesday morning, satellite imagery revealed a disturbance about 700 miles east of the Windward Islands – called Potential Tropical Cyclone 9 or PTC9. In satellite imagery, the rotation of the PTC9 appeared wide and elongated. Although the system has a lot of rotation or vortex, it will not be able to consolidate and strengthen until that spin becomes more concentrated. This could somewhat halt its development.
However, there was a significant increase in the area and intensity of the thunderstorm from Monday to early Tuesday. This is a sign that PTC9 is starting to organize.
Buoyancy data support the upward trend observed with PTC9. One buoy under an array of rotating clouds reported Tuesday morning that winds were blowing 40 miles per hour fast and air pressure would drop. Tropical storm winds start at 39 miles per hour.
The winds are approaching a tropical storm of an uninterrupted 39 miles per hour, but whether they are named depends on the winds planned around a clearly defined center. That’s what hurricane hunters will be looking for on Tuesday afternoon.
Two factors driving the activation are warmer sea surface temperatures as the storm moves west-northwest, as well as lower dry weather that affected Sunday’s storm on Monday.
The unorganized nature of a storm makes it difficult to predict and trace its intensity, as it can cause errors in the initial conditions on which computer models base their projections.
The National Hurricane Center highlighted the issue in a discussion on Tuesday morning, writing: “It cannot be stressed that as the system is still in its infancy, there is above-average uncertainty in both short- and long-term path and intensity. forecasts. ”
Depending on the PTC9 route, gusty winds and heavy rain are possible in the Leeward Islands late Tuesday and Wednesday, and in Puerto Rico on Wednesday or Thursday. The rain is good news for Puerto Rico, which has recently experienced a severe drought.
Following possible clashes with Puerto Rico and Hispaniola, an expanding high-pressure system over the Atlantic could force Isaiah to soon become a west-northwest direction and bring the Bahamas and the southeastern U.S. closer this weekend.
The National Hurricane Center expects Isaias to maintain the intensity of tropical storms due to strong headwinds that could limit its intensity before it passes near or through several Bahamas, before landing in Florida over the weekend.
The hurricane season historically peaks in mid-September, so the months of the season are left to go.
