Here's what to know as the scope of damage from #Hawaii's #floods becomes clearer
By AUDREY McAVOY and GENE JOHNSON
March 23, 2026 at 3:18 pm PDTHONOLULU โ "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 stateโs 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 โ though they were later lifted โ 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 islandโs 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."

Got another emergency warning.
#SantaBarbara #flashflood -
Power came back on around noon and I got in the shower which slowly transitioned from between lukewarm and brisk pretty much the whole time. So, I didn't have to go to my friend's place for dinner (delicious sausage sauce pasta) and board games (Kill Doctor Lucky) whilst simultaneously greasy and flakey.
I did need to bum a ride because the rain flooded our garage parking like always. I ordered some over-the-shoes rain covers for next time.

Greater LA area is going to get hit with a high end rain and wind event starting sometime Wednesday. To read NOAAโs forecast discussion, open the map, click inside any red outlined area and follow the link. The text screenshot is from the discussion for the greater Los Angeles/Oxnard area.
I am posting this on Tuesday morning. The shaded areas on the map show NOAAโs data for the likelihood of excessive rain on day 2 - i.e. Wednesday. Per NOAA, the colors mean as follows:
Pink shading = High (High) [At least 70% Chance of Flash Flooding] - Widespread flash floods are expected. Conditions include severe widespread flash flooding. Areas that do not normally experience flash flooding have conditions where lives and property are in greater danger.
Red shading = Moderate (MDT) [At least 40% Chance of Flash Flooding]- Numerous flash floods are likely- Numerous flash flooding events with significant events are possible. Many streams may flood potentially affecting large rivers.

Boy, I would not like to be those people. If the washouts are bad enough, they leave your car up there until they can build an emergency road. (although, being stranded there is probably bad too) #SanBernardinoCounty #mudslides #flashflood #CAwx

Flash flood wiped out a road there earlier today, seems like they have been dealing with that for hours. (Milpitas Wash, somewhere in the area of Cibola) #CAwx #flashflood #flooding

Extreme rainfall currently showing in northern Italy, near Lucca.
How long until we see the videos online of the #flashflood #flooding in the area? A few hours?

Good news (so far) on that extreme flash flood in Imperial County on Monday (apparently, the US Coast Guard was called for the rescues... if you saw the CHP logs I pulled yesterday, at some point the local Search and Rescue team said "call the Marines" because they were not trained for water resuces). :
KPBS: "The most severe flooding took place near Westmoreland, just south of the Salton Sea, IID officials said. There, floodwaters washed across State Route 86, trapping cars and trucks and prompting the United States Coast Guard to launch a helicopter from San Diego.
Jeremy Hamilton, a records clerk with the Imperial County Sheriffโs Office, said they had not received any reports of any deaths related to the storm...."
