A large, extratropical low-pressure area developed over the northeast Atlantic Ocean on September 14, following the interaction between a surface front and an upper-level low. The low peaked with sustained winds of 75 mph (120 km/h) on September 15. Although the low weakened as it headed south-southeastward, the wind field contracted and convection began forming closer to the circulation due to marginally warm sea surface temperatures and sufficient atmospheric instability. By 00:00 UTC on September 17, the system developed into Subtropical Storm Alpha roughly 405 mi (650 km) east of the Azores. Alpha continued to strengthen and attained its peak intensity as a subtropical system around 00:00 UTC on September 18, with maximum sustained winds of 50 mph (80 km/h) and a minimum pressure of 996 mbar (29.4 inHg). At 18:40 UTC that day, the cyclone made landfall about 10 mi (15 km) south of Figueira da Foz, Portugal. Around 00:00 UTC on September 19, Alpha weakened to a subtropical depression inland over north-central Portugal. Three hours later, it degenerated to a post-tropical remnant low near Viseu, Portugal and dissipated shortly thereafter. In preparation for Alpha on September 18, orange warnings were raised for high wind and heavy rain in Coimbra and Leiria districts of Portugal. Alpha and its associated low produced a wind gust up to 55 mph (89 km/h) at Monte Real. High winds downed many trees and caused numerous power outages in coastal Portugal. The storm also spawned at least two tornadoes, both rated EF1 on the Enhanced Fujita scale. In Spain, the front associated with Alpha caused a train to derail in Madrid, while thunderstorms on Ons Island caused a forest fire. There were no reports of injuries or deaths related to Alpha while it was a subtropical cyclone, but its remnants caused one fatality in Spain, as a woman in Calzadilla died after a roof collapsed upon her. Overall, Alpha caused at least $20 million in damage.
This was created the same day Alpha became subtropical! (kinda) Music: Dimrain47 - Buzztone Symphony Force Thirteen - In Summary (2020) ----------------------------------------------------- Inspired by and ----------------------------------------------------- Tags (ignore):
