After forming as a tropical wave off the west coast of Africa on 19 September, Lorenzo tracked eastwards and appeared in the Atlantic Ocean, where it quickly formed into a Tropical Storm. By 25 September it had intensified into a Category 1 hurricane and continued to travel eastwards.
On 26 September it underwent a period of extremely rapid intensification, becoming a Category 4 hurricane. At this point, Lorenzo had become one of the largest and most powerful hurricanes on record for the central tropical Atlantic (Figure 1).
After a short period of weakening, the hurricane again underwent rapid intensification, becoming a Category 4 hurricane (Figures 2 and 3). On September 27, the French ship Bourbon Rhode, with 14 crew members on board, issued a distress signal after sailing through Lorenzo. Although, three crew members were rescued, four were declared dead and seven remain missing.
The animation in Figure 3 shows 24 hours in the life of Lorenzo, using the GOES-16 Geocolor product with a GLM overlay. Lightning can be clearly seen the spiral bands of Lorenzo, but not so much in the centre.
By 29 September it was Category 5 storm and at this point it became the most intense hurricane to travel so far north and east in the Atlantic Ocean.
Despite weakening Lorenzo continued travelling north-eastwards to the Azores, becoming the worst storm for two decades to hit the region.
By 3 October, it had become an extratropical storm, with wind gusts of up to 106 km/h (66 mph) in western parts of Ireland, Northern Ireland Scotland, Wales and South-West England. The storm caused some coastal flooding and travel disruptions across those areas.
By the time it became extratropical Lorenzo had spent more days as a major hurricane east of 45 °W than any previous cyclone on record.
