Here's what to know as the scope of damage from #Hawaii's #floods becomes clearer

HONOLULU — "The worst #flooding to hit Hawaii in two decades swept homes off their foundations, floated cars out of driveways and left floors, walls and counters covered in thick, reddish volcanic mud.

"Crews continued to assess the destruction Monday, but authorities said hundreds of homes had been damaged, along with some schools and a hospital.

"No deaths have been reported, but more than 230 people had to be rescued. Rain continued to the southeastern part of the state and a section of the #BigIsland was under a #FlashFlood warning.

"Gov. Josh Green said the cost of the storm could top $1 billion, including damage to airports, schools, roads, homes and a Maui hospital in Kula. He called it the state’s most serious since flooding since 2004, when floods in Manoa inundated homes and a University of Hawaii library.

"On Oahu's North Shore, famed for big wave surfing, the waters rose quickly after midnight Friday as heavy rains fell on soil already saturated by downpours from a winter storm a week earlier. Raging waters lifted homes and cars. The storm prompted evaluation orders for 5,500 people north of Honolulu — though they were later lifted — and more than 230 people were rescued from the rising waters.

"Some residents fled on surfboards as water reached waist or chest high.

"Farms around the state reported more than $9.4 million worth of damage as of Monday, according to a survey conducted by Agriculture Stewardship Hawaii, the Hawaii Farm Bureau and other organizations. Oahu farmers reported more than $2.7 million in crop damage.
Winter storm systems brought severe deluges

"Officials blamed some of the devastation on the sheer amount of rain that fell in a short amount of time.

"Parts of Oahu received 8 to 12 inches (20 to 30 centimeters), the National Weather Service said. That was on top of another recent storm that had dumped vast amounts days earlier. Kaala, the island’s highest peak, got nearly 16 inches (40 centimeters) late last week, on top of 26.6 inches (67.6 centimeters) between March 10 and 16.

"Winter storm systems known as '#Kona lows,' which feature southerly or southwesterly winds that bring in moisture-laden air, have been responsible for the deluges in the past two weeks. The intensity and frequency of heavy rains in Hawaii have increased amid human-caused #GlobalWarming, experts say.

"The worst of the storms appeared to be over by Sunday afternoon."

When the Sky Breaks: Arizona Hail and Louisiana Floods, or How I May Have Cheated Death Twice More on a Greyhound Bus

I realize now, looking back at my original plot armor post, that I made a promise I somehow failed to keep. I told you there were more tornado encounters to share, specifically mentioning a third one, and then I just left you hanging like a cliffhanger in a television show that gets canceled before the next season. So here I am, making good on that promise, though I have to warn you upfront that these next two encounters exist in a strange gray area between definite tornado stories and maybe […]
