Kawaihae dirt storm

Kawaihae dirt storm

The winds were blowing here last week, 30+ mph on a consistent basis. But one afternoon the winds picked up even more and triggered dirt storms off the hills above Kawaihae.

The wind whistled down the slope from Kohala Mountain and dry dirt was gathered up, whirled around, and blasted down the slope toward the ocean. This happened for an hour or so. Sometimes, white sand from the beach in Kawaihae harbor was similarly stirred up.

The unfortunate aspect of this display was that it visibly demonstrated the problems with erosion when the ground is dry. If it’s not the wind, then any rainfall washes the soil down gullies and into the ocean. All this dirt being deposited in the relatively shallow waters off the coast degrades the water quality and can have a seriously adverse effect on corals in the area.

I told you so

Mud covered car

This week’s Sunday Stills challenge theme is ‘On the road’ (more responses here), and I thought of this image.

One of my regular walks is a loop around Upolu Airport, at the northern tip of the Big Island. It’s a dirt road and rough in places, but excellent for walking, especially along the coast. There’s a spot where this loop reaches the coast where visitors, en route to Mo’okini Heiau and King Kamehameha’s Birthplace, pause to view the coast and get their bearings.

On this day, I ran into two older men in the car in the photo and they asked me about driving to the heiaus. I said it was possible (I’ve seen a Smart Car out there before), but there were two things to watch out for. The first was clearance. As you can see, their car didn’t have a lot of that and the dirt road is studded with rocks, some of them capable of disemboweling a vehicle. The second thing I mentioned was that the road could have significant mud puddles. I hadn’t been down that way in a while and so didn’t know the state of the large puddles that form when there’s rain. But I said they could drive down past the house and they’d see the first one. I cautioned that if there’s mud I wouldn’t recommend them driving through it. A Jeep would be OK, but not that car. The mud can be quite deep, which is bad enough for a low-clearance car, but that mud can also conceal those disemboweling rocks.

The two men thanked me for the information and drove off. I carried on with my walk.

About 45 minutes later I neared the parking lot and saw their car pulled over on the side of the road. My first thought was that the car looked as if it had been coated with chocolate. The brown layer across the front, top, and back, was perfectly smooth. The sides were more splattered, but it was clear that an impressive amount of mud had somehow been made to coat most of the car.

I had a momentary panic. Had I somehow forgotten to mention the rough road and the mud? Had I said, ‘Don’t worry about the conditions. Just go for it.’ One of the men I’d seen earlier was talking on a phone next to another car. The other was standing besides the muddied car. I walked up to him and before I could say a word he said, “Do you know what the four most satisfying words in the English language are?” I looked blank. “I told you so,” he said. I told him that wasn’t what I was thinking and that was true. I was more curious about what the heck had happened.

He said they’d come to the first mud puddle and his friend, who was driving, said the thing to do was to go through at speed. He’d urged caution, but they zoomed into the mud, disappeared from view, and emerged in a different color car. Oh, and then the car died. They got it going again and somehow coaxed it back to the paved road near where I found them. Quite how they managed this, I don’t know. It meant driving back through the mud and then easing along for another mile to the paved road. They did this very slowly. Once they reached this road, they sped up and the car promptly died again.

I looked into the engine compartment and it was as liberally coated with mud as the exterior. They’d removed the air filter because that was full of mud. Chances were that several other significant engine cavities were similarly choked.

I waited with them until a tow truck arrived and then left. I never learned how bad the car was damaged or how they explained it away. I didn’t really want to know. Instead, I preferred to remember the image of that chocolate-coated car and my image of the magnificent ride that made it that way.

Kites

Kite with tail

KitesOn one of my recent walks, I saw half a dozen kites soaring in the air and I realized it might be the first time I’ve seen kites around here. This is somewhat surprising since North Kohala is notoriously windy and seems like it would be a mecca for kite flying.

Kites are no longer simple diamond shapes on a wooden cross and these were by no means the most exotic kites available these days. But I did like the pterodactyl below and the others were also striking, particularly when they caught the sunlight.

NEXRAD radar facility

NEXRAD radar (golfball)

NEXRAD is the Next Generation Weather Radar operated by the National Weather Service, Air Force Weather Agency, and Federal Aviation Administration. There are 160 sites, most of which are spread across the United States. Four of the sites are in Hawaii, two of which are on the Big Island. This site is on Kohala Mountain, northwest of the summit. It’s known to local pilots as the golfball, for obvious reasons.

This weather radar network is a staple of online news and weather sites and shows the location and movement of rain and clouds. The Kohala radar features a pie-slice area of permanently clear weather to the northeast, which I assume is caused by the nearby topography.

I use the weather radar quite a bit and find it fairly helpful, though the weather here is quick to change. Weather forecasts, on the other hand, I find are more of a 50-50 proposition – they’re either fairly right (not too hard to figure out when the trades are blowing) or wildly wrong (all other situations). However, since it’s almost always warm here, I can’t complain too much.
