Three tropical waves are floating in the Atlantic Ocean, one of which will be named “Bonnie” and another could flood southeastern Texas with torrential floods. The peak of the hurricane season is still after 2½ months, but the Atlantic basin quickly came to life.
The strongest of the three meanders westward and intensifies about 950 miles southeast of the Windward Islands of the Caribbean, likely to develop in the coming days as it approaches the Lesser Antilles. The system, called Invest 94L by the National Hurricane Center, could turn into a tropical depression or storm and potentially turn into Bonnie by mid-week.
NOAA predicts the seventh consecutive busy season of hurricanes in the Atlantic Ocean
The same storm could eventually become stronger in the Caribbean, unlikely to become the first Atlantic hurricane of the season and swirl over warm ocean waters by the end of the week.
After him, another tropical wave shows some signs of organization, but it probably won’t become as remarkable as its predecessor. Nevertheless, it is being watched.
Meanwhile, a third system is beginning to materialize in the northwestern Gulf of Mexico. This, while unlikely to strengthen enough to make a name for itself, is likely to turn into a tropical storm and is a problem for several large metropolitan areas in Texas where severe flooding can be expected.
Atmospheric scientists and hurricane experts have already warned that this season could be rough, predicting that it will be abnormally active or “hyperactive”. The existence of the La Niña model, combined with storage of extremely warm sea surface temperatures in the Gulf of Mexico and countless other factors, prefers particularly busy a few months ahead.
Invest 94L – the one you need to watch carefully
On Monday morning, the Invest 94L was about 300 miles northeast of French Guiana in South America and drifted west-northwest at speeds of 15 to 20 miles per hour. In satellite imagery, it looked significantly healthier than 48 or even 24 hours ago, was excited by rain and thunderstorms, and thrived thanks to reduced shear. A Hurricane Hunter plane from the National Oceanic and Atmospheric Administration is due to investigate the system on Monday afternoon.

Destructive cutting of the wind or change of wind speed and / or direction with height may to be unfavorable to a developing tropical cyclone, to play something like pulling a rope that could tear it apart. In this case, however, the 94L is tucked in a pocket by a relatively cool cut, which has allowed for organization over the past few days.
There is a wide circulation at a low level, but it remains to be seen whether a more concentrated, cohesive vortex can form. If a vortex materializes near the surface, it will need an upward flow of thunderstorm to stretch it vertically. This is one of the first steps towards the formation of a tropical depression, a precursor to a tropical storm.
The National Hurricane Center estimates a 90% chance that the 94L will eventually turn into a tropical storm, with a 70% chance of doing so in the next two days. Until late Tuesday or Wednesday you can flirt with the force of a tropical storm while breezing through the Windward Islands with torrential rains and gusty winds. In some places, a total of 4 to 8 inches of rain can be seen.
Once the maximum wind has exceeded 39 mph around A notable center, the 94L will become Bonnie, the second-named storm of the Atlantic hurricane season in 2022. It could intensify with the force of the Caribbean hurricane between Wednesday and weekend before potentially reaching land somewhere on the Costa Rica, Honduras, Nicaragua or Belize, affecting these countries or Guatemala.
Floods and mountain mudslides, along with some damaging wind and coastal waves, remain on the table.
Second system “Main Development Region”.
After 94L is the second tropical wave over the main development region of the Atlantic Ocean (MDR). This is the wide stretch of tropical ocean waters between North South America and Northwest Africa, where so-called storms routinely develop in mid to late summer. Only three registered tropical systems were listed in the MDR in June.
A tropical wave in the Atlantic Ocean is now given a 60% chance of a tropical cyclone forming over the next 5 days by the National Hurricane Center. Only 3 recorded storms were named in June in the tropical Atlantic Ocean (south of 20 ° N, east of 60 ° W): Unnamed (1933), Ana (1979), Bret (2017). pic.twitter.com/MM1CZIOohC

The time models are divided in their weak wave simulations, but there is about a 1 in 5 chance of possible development. Nevertheless, it seems that there may be additional rain on the Leeward Islands over the weekend.
Heavy rain on top of the Mississippi Delta has been lurking in the northern Gulf of Mexico for the past few days and will slow and fester before gradually shifting west. It can develop a slight rotation due to its positioning at the end of the cold front.
It will not turn into depression or get a name; The National Hurricane Center gives it only a 20 percent chance of development. But it will contain a lot of moisture.
The jury still doesn’t know where the system will go, but it could bring significant rainfall to coastal Texas somewhere between the Houston-Galveston subway and Matagorda Bay if and when the mass of rain shifts to shore. Some models simulate hovering over the west bay and possible distraction. How it will develop in the coming days remains to be seen.
