Toward the middle of the afternoon, Biff looked up to see Li coming aft. Biff was at the tiller. He noticed a frown on his Hawaiian friend’s face.

“What’s up, Li? You sight something?”

“No, Biff,” Li shook his head. The serious expression on his face had deepened to one of worry.

“Then what’s your trouble? You look like you got trouble.” Biff smiled.

“I’m afraid we both may have,” Li answered. “Have you noticed it getting any warmer?”

“A little, perhaps. Wind’s freshened a bit, too.”

“That’s it. I’m afraid we’re in for some Kona weather.”

“Kona weather?”

“Yes, that’s what we call a wind coming up from the Equator. Sometimes it reaches gale force. Always there’s heavy rain.”

Biff looked astern. On the southern horizon, he could make out huge thunderheads.
