Tropical Storm Isaias is a currently active tropical cyclone threatening landfall in the Dominican Republic. The ninth Tropical storm of the 2020 Atlantic hurricane season, Isaias originated from a tropical wave off the coast of Africa that was first tracked by the National Hurricane Center on July 23, 2020. The tropical wave gradually became more organized, and intensified into Tropical Storm Isaias on July 30. This marked the earliest ninth named storm on record, surpassing 2005's Hurricane Irene by six days.
Numerous Tropical Storm Watches and warnings were issued for the Lesser Antilles, Greater Antilles, the Bahamas, Cuba, and Florida.

Unknown Storm type
Tropical cyclone 
Subtropical cyclone 
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression The National Hurricane Center first began tracking a vigorous tropical wave off the coast of Africa on July 23. The wave gradually organized and became better defined, developing a broad area of low pressure. Though the circulation was broad and disorganized, convection continued to increase over the system. Although the system still lacked a well-defined center, its threat of tropical-storm-force winds to land areas prompted its designation as a potential tropical cyclone at 15:00 UTC on July 28. The system moved just south of Dominica on July 29, and at 03:00 UTC on the following day, it organized sufficiently to become a tropical cyclone. Due to its precursor disturbance already having gale-force winds, it was immediately declared a tropical storm and given the name Isaias. When Tropical Storm Isaias formed, it became the earliest ninth named storm on record, shattering the record of Hurricane Irene in 2005 by 9 days.
Preparations
In anticipation of the storm, the state of Florida closed COVID-19 testing sites due to potential impacts from Tropical Storm Isaias on July 30.

Impacts
Puerto Rico
In Puerto Rico, about 312,500 customers lost power and about 150,000 customers lost water service due to electric blackouts and blocked intakes. The entire town of Yauco had not power, and all roads leading to the town were either flooded or blocked by fallen trees. Many surrounding towns in eastern Puerto Rico also had no drinking water nor electricity from a lack of access to the areas of damage. Three gates on the Carraízo reservoir dam in Trujillo Alto, Puerto Rico, were opened because of runoff from Isaias. Due to the extensive damage, President Donald Trump approved an emergency declaration request from Puerto Rico's Gov. Wanda Vázquez Garced.
Dominican Republic
One person was electrocuted to death in El Seibo Province, in the Dominican Republic. He was milking cows when a power line fell on his horse a few feet away from him, killing him and the animal.
