Rarest variety of rainbow?

When it comes to the summer wet season in south Florida …

That means blue skies all morning and downpours in the afternoon, right?

Here’s an early morning land-breeze fed cumulonimbus clouds.
I saw it during my commute ride into work over the Ten Thousand Islands

By afternoon downpours I mean the giant cumulonimbus cloud which at the hands of inland heating of the land’s surface, i.e., causing air to rise, which is in turn replaced (and fueled) by a stout sea breeze blowing in from the coast. But don’t forget, that same sea breeze reverses direction during the night to form its twin opposite, the land breeze, which blows towards the coast towards the tug of sea-warmed air rising over the offshore shallows of the gulf.

When the morning land breeze collides head on with the regional winds – POP! – coastal cumulonimbus clouds take form.

Miami is famous for its morning showers because of the orthogonal orientation of its coast with the prevailing path of the eastward blowing Trade Winds. But they aren’t confined just there. Each summer on occasion I see them line up like a morning parade along the Ten Thousand Islands Coast to the south on my ride into work.

Here’s a rare sighting of a morning rainbow as seen from Ochopee

Thus, morning clouds can be quite common.

Except in this case because of the rainbow.

I usually only see those in the afternoon.
