A ship horn signal that could be heard more often on the river in August

Yesterday I heard a ship do its five-blast warning signal on the river, letting a sailboat know of its presence and cautioning it to stay out of the ship's path.

This is a standard horn signal that ships and boats use when they see a potential issue developing and want to head off any possible problems with a nearby vessel.

With Buoy 10 fishing season approaching, it's a signal we land-dwellers who live near the river may hear more often in August.
