Hurricane Danielle: Next week will cause heatstroke and thunderstorms!

Hurricane Danielle is located off the Azores and is slowly moving towards Western Europe. In the back, Earl, a tropical storm that formed north of Saint Martin, is heading for Bermuda. These two phenomena seem to have to take the direction of Europe bypassing the Azores anticyclone, the classic route of the old hurricanes, some of which every year reach the British Isles in a phase of depression.

Danielle, an atypical tropical system

Originally a tropical storm, Danielle developed particularly at high latitude over the North Atlantic. Only 1.4% of tropical storms originated further north than Danielle in the past 170 years. Sea water temperatures, which are about +4 to + 5 ° C higher than the average of this area (water is about 25 ° C here) constitute an energy that cyclonic systems draw on to develop. This fuel allows them to stay in these areas, which are usually less conducive to their formation. However, during her trip to Europe, Danielle will fly over increasingly colder waters, around 22 ° C. This overflight should make it lose its tropical characteristics and make it become, in the next few days, a completely classic depression in our temperate latitudes.

It should be noted that the sea temperature is not the only parameter necessary for the development of a hurricane. It requires a calm surrounding atmosphere without strong winds. This is not the case in our latitudes, where the approaching tropical systems are absorbed by the prevailing western flow. This is what will happen with Danielle who will be recovered in the wake of the cold fall she is shooting in the west of Ireland.

According to the latest models, Danielle will be slowed down and then likely blocked off the Atlantic by Saturday, her effects here should be limited.

Sharp rise in temperatures and new thunderstorm risk next week

Until Saturday the hurricane will therefore continue its path and should become a simple depression in temperate latitudes before reaching the coasts of our continent. This classic development could cause an increase in the atmospheric pressure field in sight, with an anticyclone swelling over the country over the weekend of 10 and 11 September. The weather could therefore be sunny and increasingly warm in the country. Temperatures could even be well above the seasonal norm early next week, with values ​​exceeding 30 ° C once again in the southwest, and then rising towards the Paris region.

This situation could also shift the wind direction towards the southern sector, and generate a marked stormy deterioration in the south of the country and in Spain, after the storms we have already experienced this week, a situation that we are already closely monitoring on The Weather Channel.
