The first tropical cyclone of the year was a tropical disturbance in the South Pacific, which formed on January 2 over the Solomon Islands.

In August, Hurricane Harvey struck southeastern Texas and subsequently stalled over the state, dropping 60.58 in (1,539 mm) of rainfall; this was the highest amount of precipitation associated with a tropical cyclone in the United States. The rains caused widespread flooding along the storm's path, particularly near Houston, resulting in more than 100 fatalities and US$125 billion in damage, tying Harvey with Hurricane Katrina in 2005 as the costliest United States hurricane. [73] In September, Hurricane Irma struck the northern Lesser Antilles and later Cuba as a Category 5 hurricane, and later Florida at a lower intensity, causing more than US$50 billion in damage and 139 deaths.
