The impending Regina storm is set to bring significant rainfall and thunderstorms to the Iberian Peninsula and Southern France in the coming days, as reported by weather service Foreca. The storm is also expected to create challenging sea conditions around the Canary Islands with wave heights reaching up to 10 meters. Given the storm's trajectory, areas in Southwestern Spain moving towards Morocco might experience severe weather, particularly impacting Southern and Eastern Spain where localized flooding is a concern.

Heavy rainfall, particularly over Eastern Spain, is expected to peak on Thursday with accumulations possibly exceeding 100 millimeters in certain areas within 24 hours. Popular tourist destinations on the Costa del Sol and the eastern coastline will be affected by these intense weather conditions. Following this period of heavy rains, weather forecasts predict a gradual improvement, although unstable conditions will persist into the weekend.

In addition to the mainland impacts, the storms are also expected to affect the Canary Islands significantly, including heavy snowfall at higher altitudes, which could hinder access to many popular hiking trails. This severe weather system is likely to create widespread travel disruptions and pose safety risks for both locals and tourists in these regions.
