Two back-to-back storms in Hawaii this March caused economic and insured losses of at least $1 billion, according to new data from Aon.

Those losses could increase as the damage is still being assessed, the report said.

Two Kona Storms hit the islands on March 10-16 and again March 19-24, bringing torrential rainfall across the entire state. Kona Storms are slow-moving low-pressure systems that typically form in the spring and fall.

The two-week period was the heaviest rainfall event Hawaii has seen since 2004. Rainfall reports from Oahu and Maui exceeded 52 inches.

Oahu, especially the North Shore, was severely impacted by the storms, which caused flash flooding and landslides that damaged hundreds of homes and washed out roads.

Many farms were hit hard. Aon estimates that farmland damage could be more than $9.4 million across the state, with $2.7 million of damage in Oahu alone.
