Twin Threats in the Atlantic: Two Weather Systems Gain Strength Heading Toward the Caribbean

The tropical Atlantic is showing signs of rapid activity with two weather systems under close watch as they move westward, posing a potential threat to the Caribbean and Cuba.

One of these systems has an 80% chance of developing into a tropical cyclone, while the second has a 50% chance over the next week.

The U.S. National Hurricane Center (NHC) reported on Thursday that they are monitoring systems AL92 and AL94.

AL92 presents a high likelihood of development, with an 80% probability, while AL94 has a medium chance, at 50% over the next seven days.

AL92: Immediate Attention Required

The more immediate concern is AL92, a tropical wave located about 1,000 miles east of the Lesser Antilles.

This system is exhibiting signs of organization, with showers and thunderstorms, and the NHC anticipates it may develop into a short-lived tropical depression within the next day or two as it moves westward.

However, the window for its development could close quickly.

Forecast and Potential Impact

According to the forecast at 8:00 a.m., by the end of Friday, AL92 is expected to enter an area with strong upper-level winds and dry air, conditions that could prevent further strengthening.

This does not mean the Lesser Antilles are out of danger. The NHC has advised residents to closely monitor the system's development, as it could bring gusty winds and heavy rain between Friday night and Saturday, regardless of whether it develops into a tropical cyclone.

AL92 currently has an 80% chance of formation both in 48 hours and over the next seven days.

This system had a 70% chance of development two days ago while moving through the tropical Atlantic, indicating that its potential for organization has continued to rise.

AL94: Gradual Development Expected

Further behind is AL94, a tropical wave situated several hundred miles south-southwest of the Cape Verde Islands.

Currently, it is producing disorganized showers and thunderstorms, but atmospheric conditions might favor gradual development as it continues its westward or west-northwestward movement through the eastern and central tropical Atlantic.

In the short term, its potential to become a tropical cyclone remains low, at 30% over the next 48 hours.

Nonetheless, this probability increases to 50% over the next seven days, and the NHC suggests a tropical depression might form by the end of the week or over the weekend.

Increased Atlantic Activity

The simultaneous emergence of both systems underscores a warning issued just hours earlier by Cuban meteorologist José Rubiera, who cautioned about a "parade of tropical waves" with development potential trailing AL92 and urged close monitoring of systems moving from Africa across the Atlantic.

"We have 92L, a system with high potential to become a tropical cyclone in the coming days. Following that, there's another one, and don't think it ends there," Rubiera warned, noting a significant increase in tropical Atlantic activity.

As these two disturbances head west, Cristóbal weakened to a tropical depression far from the Caribbean. On Thursday, the system was about 600 miles west of the Azores and was expected to dissipate, posing no threat to Cuba.

Currently, the NHC has not identified a direct threat to Cuba from AL92 or AL94, though it is crucial to stay informed on weather updates.

The presence of two areas with significant development potential confirms that the Atlantic is entering a more active phase, necessitating vigilance on systems advancing from the east toward the Antilles.
