Three 2015 storm names are attached to severe enough storms that the World Meteorological Organization announced they’ll be replaced when the 2015 list is reused in 2021.

Erika will be replaced with Elsa, Joaquin with Julian, and Patricia with Pamela, according to a news release from the National Oceanic and Atmospheric Administration.

Tropical Storm Erika caused more than a foot of rain on the island of Dominica and was responsible for 30 deaths with an additional death in Haiti.

Hurricane Joaquin grew to a Category 4 hurricane and caused widespread damage on a number of Bahamas’ islands, including San Salvador and Crooked Island. In all, 34 people died in the storm, including the 33 crew members of the cargo ship El Faro, which sank near Crooked Island, according to NOAA.

The Pacific Ocean Hurricane Patricia became a Category 5 storm and made landfall in October in a sparsely populated part of southwestern Mexico as a Category 4.

Normally, storm names are reused every six years in the Atlantic Ocean basin. Names are retired when the storm is so deadly or costly that “future use of the name would be insensitive,” according to NOAA.
