Hawaii faces catastrophic flooding as multiple storm systems have battered the islands since February, causing at least $1 billion in damage according to Governor Josh Green. The latest system pounded Maui on Tuesday, bringing the final wave of rainfall to an already waterlogged state. Forecasters expect the storms to completely exit by Wednesday.

Hana, on Maui's eastern coast, has recorded over 40 inches of rain since February 1 - the highest amount ever measured in that timeframe. The Daniel K. Inouye International Airport in Honolulu has seen nearly 16 inches, making it the fourth-rainiest period since records began in 1941. From March 10-16, a kona low brought over two feet of rain to many locations, with some areas receiving more than four feet.

The saturated ground couldn't absorb more water when the next storm arrived Thursday, causing flash flooding across Oahu and Maui. Emergency crews rescued over 200 people on Oahu as floodwaters threatened a local dam. Properties in Kihei were destroyed by raging floodwaters. Massive snowfall accumulated on Mauna Loa and Mauna Kea, while winds exceeded 100 mph at highest elevations.

With the storm system departing, typical trade winds are expected to return. Meteorologist Alex Gibbs said "more pleasant weather is on the way" as Hawaii begins assessing the extensive damage from what experts agree has been one of the state's rainiest periods in recent memory.
