Hurricane Helen (2018)

Remnants from Florence and Gordon, along with a very violent tropical wave formed Helene on August 26. Gaining strength, Helene struck Azores at Category 3 strength.

Flash flooding and high winds caused devastating damage on the island. As the system exited Azores, wind shear caused Helene to weaken to a Category 1 storm before reaching peak intensity 160 miles northeast of Morocco.

An eyewall replacement cycle took place, weakening Helene momentarily to a Category 2 before coming a Category 3 for a final time before hitting Algeria as a Category 2. Algiers suffered heavy rainfall, and in some areas, the rainfall that was accumulated was up to 9.76 inches.

However, the system gradually weakened in Africa after causing heavy rainfall on the continent after killing 16, injuring over 12,000 due to high populations in Africa and $328 million in damages.
