I been into the Lahaina fire situation way too deep this week, causing a lack of sleep. Contributing factors: We have vacationed in Maui for 30 years and have considered moving there; 20 years of volunteer firefighting experience with several major fires under my belt; I'm also pretty much a weather nut as I do a lot of forecasting for my ski blog.
Things to note in this thread:
• Although the mainstream media has hyped the hurricane connection to this fire, Hurricane Dora had very little to do with the winds that day. The high pressure system north of the islands was the driving force for those winds. That's not as sexy as saying hurricane. The winds were blowing from the east to west. The West Maui mountains rise several thousand feet, and the winds rise up over the mountains, then back down the mountain. That "mountain wave" causes increased windspeed. Additionally, as the winds move downslope, they are compressed as they hit the flat land. That causes heat. So you have very hot and dry fast moving winds. Most estimates are in the 80 mph range.
• This fire has very much to do with the abandonment of pineapple and sugar cane fields on the island. When we first started visiting the island in the 80's, those plantations covered much of the flatter lands. Around Lahaina, it was mostly pineapples. As growers consolidated and were bought out by big corporations, pineapple and sugar production was outsourced to cheaper countries. Those big plantations now are covered by tall non-native grasses, which burn far more easily than irrigated crops. This is a huge problem. Landowners should be forced to either grow crops or return the land to a more native state.
• In California, we mitigate risk by shutting down the power grid during big wind events. In Maui, this is not possible, as much of the water supply on West Maui must be pumped. Shutting off power shuts off the water supply. That is exactly what happened when the wind and fire took out the power...no water. As the area is rebuilt, it's pretty certain that putting power lines underground will be a priority.
• Ultimately the biggest question was the lack of public warnings and considerations of evacuations, including not using the siren system. If you look at YT, there are many video showing how windy it was all day before the fire started. The evacuation should have started that morning. This is not the first big fire maui has seen.
• The road around the north end of Maui is way more intense that the road to Hana. We have done both all of the way around and neither bothered us as we live in mountainous areas with similar roads. We also rent the smallest rental car we can get. That evacuation around the north side would be a huge challenge for city dwelling tourists that rented the largest SUV they could get...at night.
