Subtropical storm Teresa forms north of Bermuda

Subtropical storm Teresa formed north of Bermuda on Friday, becoming the 19th named storm of the 2021 Atlantic hurricane season.

Unlike tropical storms, subtropical storms do not have the potential to quickly turn into hurricanes, according to the national weather service.

Teresa has a small window to “escalate slightly”, but it is more likely to remain a subtropical storm until it dissipates, the National Hurricane Center said.

A developing system forming off New England is expected to absorb Teresa within a day or two, forecasters said. The storm should not threaten the land.

The Hurricane Center said Teresa would most likely be the ninth “shortie” – a short lived and relatively weak system – of the hurricane season. Recent examples of this kind of storm are Odette, Peter and Rose.

“There has been a proliferation of these ‘shorties’ in recent years, which is mainly due to technological improvements, not natural or man-made climate variability,” said Dennis Feltgen, meteorologist and spokesperson for the National. Hurricane Center, in a statement. E-mail.

After Teresa, there are only two names left, Victor and Wanda, on the planned list of 21 storm names. If more storms do form, the National Weather Service will switch to a list of additional names, only the third time in history – but the second in two consecutive years – that it has had to do so. Hurricane season officially ends on November 30.

It has been a dizzying few months for meteorologists, as the onset of the peak hurricane season – August through November – resulted in a series of named storms that quickly followed one another, causing flooding and damaging winds in some. parts of the United States and the Caribbean.

The links between hurricanes and climate change are becoming increasingly evident. A warming planet can expect stronger hurricanes over time and a higher incidence of more powerful storms, although the total number of storms may decline as factors such as greater wind shear. strong could prevent the formation of weaker storms.

Hurricanes also get wetter because the warmer atmosphere contains more water vapor. Scientists have suggested that storms such as Hurricane Harvey in 2017 produced much more rain than they would have had without the human effects on the climate. In addition, rising sea levels contribute to increased storm surges, the most destructive element of tropical cyclones.

Ana became the first named storm of the season on May 23, making it the seventh consecutive year that a named storm has developed in the Atlantic before the official start of the season on June 1.

In May, scientists from the National Oceanic and Atmospheric Administration predicted there would be 13 to 20 named storms this year, of which six to 10 would be hurricanes, including three to five major Category 3 or more hurricanes in the Atlantic. .

NOAA updated its forecasts early August, predicting 15-21 named storms, including 7-10 hurricanes, by the end of the season.

Last year there were 30 named storms, including six major hurricanes, forcing meteorologists to exhaust the alphabet and switch to using Greek letters.

These are the most named storms on record, surpassing the 28 of 2005, and the second-highest number of hurricanes.
