Tourists have been warned to prepare for possible tropical cyclones in Spain.
Rare Mediterranean storms, called medicans, have increased in number due to high temperatures.
They can cause life-threatening torrential rains as well as flash floods.
The increase in sea temperature, as Spain has also witnessed, also increases the probability of a cyclone-like weather phenomenon.
Tourists traveling to Spain in the coming weeks have been warned against getting caught up in the drugs.
Sea temperatures in parts of the Mediterranean coast have reached 30°C, which is around five degrees higher than the typical summer average.
And on the island of Formentera, off Ibiza, meteorologists recorded the highest temperature in the history of the Balearic Islands on Saturday.
The mercury had risen to a sweltering 44.5°C amid the heat wave that is hitting countries across Europe.
“The higher temperatures of the Mediterranean provide a greater source of energy for drugs and amplify their destructiveness,” said oceanographer and meteorologist Yurima Celdrán.
The academic added: “Sea temperatures this autumn are expected to be higher than normal and if the necessary atmospheric conditions are met, it would not be unreasonable to think that the Mediterranean could host a medicane this year.”
As temperatures drop, the chance of storms in general could increase, experts say.
Marine ecologist Carlos Duarte told the Spanish newspaper El Mundo: “The biggest and most imminent risk of this marine heat wave this year is that the Mediterranean is very hot and when it cools down in autumn, it can cause extreme episodes of storms.”
“In some places, drugs could occur, which may be more intense than what we have experienced so far.”
Five medicines have affected the Mediterranean basin in general since 2011.
In 2019, a medicane was accompanied by torrential rain and huge thunderstorms, which paved the way for flash flooding.
The provinces of Alicante and Murcia were the hardest hit, and the “tropical cyclone” left seven dead.
Authorities estimated the financial cost following the devastation to be around £1 million, the costliest natural disaster in Spain’s recent history.
Concerns about extreme weather have been on the rise across the country.
The specialist weather website tiempo.com, after reporting how winds can reach speeds of up to 93mph during a medicane, added: ‘After the hottest July on record, the Mediterranean has turned into a hot soup with temperatures between 27°C and 30°C. .
“It is clear that if the temperature of the sea continues to rise, it increases the possibility that the right marine conditions exist for the formation of adverse phenomena such as drugs.”
Cyclone Ianos is considered to be the last tropical-type cyclone or medicane in the region.
It affected the eastern Mediterranean on September 17 and 18, 2020, in particular Greece.
The cyclone reached gust speeds of 121 mph, equivalent to a Category 2 hurricane on the Saffir-Simpson scale, before making landfall in southwestern Greece.
Five people were killed and a state of emergency was declared on several islands, including Zakynthos.
