Bermuda experienced a prolonged period of thunderstorms, lightning and heavy weather from yesterday into the early hours of this morning as a low-pressure system moved across the island.

The unsettled conditions prompted questions about the severity of the storms and what residents can expect as Bermuda moves deeper into the Atlantic hurricane season.
TNN News spoke with Bermuda Weather Service meteorologist Anton Wiltshire, who explained that the activity was associated with areas of convergence at the surface, supported by an upper-level shortwave trough.
“At the surface, we had areas of convergence that moved over the island, which was assisted by a shortwave trough in the upper levels,” Wiltshire explained. “That aided in the production of thunderstorms that lingered for much of yesterday into today.”
While the intense lightning and thunderstorms may have been frightening for some residents, Wiltshire said the conditions were not considered unusual for Bermuda during the summer months.
“It’s more or less what we can expect during the summer,” he said. “We’re going to get these occasional thunderstorms. Sometimes they’re going to come with these gusty winds, but it’s nothing to be too worried about.”
Wiltshire encouraged residents to take the necessary precautions whenever thunderstorms move across the island, particularly when lightning and strong winds are present.
Meanwhile, attention is turning toward the Atlantic as Bermuda enters the more active portion of the hurricane season.
Wiltshire said the next tropical wave being monitored is expected to move off the African coast on Monday and currently has a 50 percent chance of development over the next seven days.
Another area of disturbed weather southeast of Bermuda is also being monitored, with a 20 to 30 percent chance of development, although Wiltshire said that system is expected to pass well east of Bermuda and is unlikely to have a significant impact on the island.
Looking ahead toward September and into mid-October, Wiltshire said the overall expectation is for hurricane activity to remain somewhat subdued.
He pointed to the expected influence of El Niño conditions, which could contribute to reduced Atlantic hurricane activity during much of the remainder of the season.
However, he stressed that a quieter season does not mean Bermuda is completely out of the woods.
“It is still possible that some could develop,” Wiltshire said, adding that current indications suggest the hurricane season could be “a bit more on the diminished side.”
With several weeks of hurricane season still remaining, residents are being reminded that tropical development can occur even during a season expected to be less active.
For now, Bermuda Weather Service continues to monitor the Atlantic while residents are encouraged to remain weather-aware and take appropriate precautions when thunderstorms threaten the island.
