The storm birds are gathering

“Graham, get your camera. Storm birds!” With that alert, I dashed out of the office at work and saw these Great Frigatebirds circling in the gray skies towards Kohala Mountain. There were 16 of them, which is the most I’ve seen at one go.

These birds are known as ’Iwa in Hawaii. This means ‘thief’ in the Hawaiian language, a reference to their practice of harassing other birds into dropping prey they’ve caught, which the ’Iwa then take for themselves.

In Hawaii, a gathering of these birds is seen as a sign of stormy weather coming, Hence the storm birds name. They were on the money again, with Tropical Storm Calvin hitting the island a few days later.

Keanuiomano Stream has been bone dry for weeks, but yesterday’s passage of Tropical Storm Calvin transformed it into a roaring river. There was a lot of rain up in the Kohala Mountain area, which is the source of the stream. It was interesting, though, that the gullies that carry water off the leeward side of that mountain were still dry, so all that rain must have fallen mostly on the windward side and the east end of the mountain.

Storm’s a comin’

This photo is from a while back but it could be right now as Tropical Storm Calvin approaches the Big Island. The storm was a hurricane while in the Eastern Pacific, but it weakened as it neared Hawaii. Yesterday afternoon, the storm strengthened again with winds up to 60 mph. Who knows what will happen to it overnight, but I’m scheduling this ahead of time in case the power goes out.

Hurricanes here have been a mixed bag. Hurricane Lane, which hit the island in 2018, stalled off the west coast of the island, bringing gray skies but little wind or rain to the west coast. The eastern part of the island had a different experience. They had 54 inches of rain in three days!
