The air is so unstable, it can trigger these things. The conditions are just very favorable for these types of situations.

With La Nina, there is a slight tendency to have wetter-than-normal conditions.

We might see some sun Sunday ... It will be partly cloudy, some staggered showers.

What's unusual is you're talking six weeks where the pattern was essentially fixed. Blocking patterns happen pretty much every year in the Pacific but six weeks is a long time.

That's quite a bit of water. Now, granted, not all if it will run specifically into a stream, but that gives you some idea of the magnitude of this.

It's still the expectation that we should see a lot of improvement on Saturday. I don't know about sunny. How often is it sunny in Hilo?

Luckily, the north side got a bit of a break last night.

Actually, it was not that wet until the last week or so.

Right now, there is quite a bit of uncertainty with the situation. We're looking for a new storm system moving in (tomorrow), and we're looking for rains, possibly to persist into the weekend. This one looks like it might produce some winds and thunderstorms where it hits hard and blasts through, affecting the entire state at different times.
