Meteorologists are watching three weather systems, any of which could become the fourth named storm of the year.

None of the systems are considered threats to the island as of yesterday afternoon.

The US-based National Oceanic and Atmospheric Administration has said that an area of low pressure several hundred miles east of the Lesser Antilles is expected to strengthen, although a flyover by a Noaa reconnaissance flight yesterday revealed little change in the system.

“Although environmental conditions are only marginally conducive, additional gradual development of this system is expected and a tropical depression is likely to form within the next couple of days,” Noaa said.

“The disturbance is forecast to move slowly towards the west-northwest, towards the adjacent waters of the northern Leeward Islands.”

Noaa estimated that the system had a 60 per cent chance of becoming a named storm by Friday afternoon and an 80 per cent chance of doing so by Monday afternoon.

If the system does become a named storm, it would be Tropical Storm Danielle.

The organisation is also watching a low-pressure system well to the island’s east — about 850 miles west-southwest of the westernmost Azores.

The system has an 80 per cent chance of becoming a named storm by Monday afternoon, but is moving away from the island.

“Environmental conditions are expected to be conducive for development, and a tropical or subtropical depression is likely to form within the next day or so, while the system drifts generally eastward,” Noaa said.

Noaa also continues to monitor a low-pressure system between the west coast of Africa and the Cabo Verde islands that has become more organised over the past day.

“Some gradual development is possible, and the system could become a short-lived tropical depression over the far eastern Atlantic during the next couple of days,” the organisation said.

Conditions are expected to become less favourable for development later this week.

Weather forecasters have said the 2022 hurricane season would be busier than average, with Noaa forecasting between 14 and 20 named storms, including six to ten hurricanes.

However, the season has had a slow start with only three named storms to date, none of which has reached hurricane strength.
