On September 20, 2017, Hurricane Maria struck Puerto Rico as a high-end Category 4 storm. Many residents spent months without power or running water. Over 59,469 Blue tarps were place on damaged home. As of early 2019 there are still 33,766 roofs in need for repairs.
MDS began early 2018 in clean-up work with small groups of volunteers, and repairing roofs.
MDS is responding in Utuado, Ponce, and Aibonito, in connection with Mennonite Churches in Puerto Rico. MDS accommodations vary by location, and may include guest houses or rented homes. Running water and electricity have mostly been restored in Puerto Rico. In some areas limited internet and cell phone service may exist.
