April 19, 2024 and what is a fair-weather water spout?

Good morning Bay Islands. Our photo of the day comes from Christina Matthews and west taken from Iron Shore on West Bay. It is a waterspout, a fairly common occurrence in our tropical waters, so I thought in comments I would talk a little about what a waterspout is and is not.

There are two types of water spouts: tornadic and fair-weather. We do not have tornadic water spouts for the simple reason that we do not have tornadoes at all this close to the equator. They typically form along the dark, flat bases of a line of developing cumulus clouds (what I like to call popcorn clouds). They develop when the air at the base of the cumulus cloud is much cooler than the temperature of the surface waters, causing an updraft. They generally don’t move very much, so they are easy for boaters to avoid, and they last an average of 5 to 10 minutes. So click a picture fast, because it won’t last long.

On satellite this morning we see some cumulus clouds north of Puerto Cortes, and who knows? Maybe they are seeing a water spout over there. These are the kind of clouds that produce them and also some small morning showers.

Here is the radar at 7 a.m. showing a line of showers north of Puerto Cortes. Unfortunately these are moving to the west away from us. We will stay high and dry. Each morning we have maybe a 5 percent chance of a shower, but Monday through Wednesday morning next week looks to be a little higher, maybe 20 percent chance of a small morning shower.

 Wind and Galaxy Wave forecast: Our east winds will remain consistent, at 15 mph from the east with 2-3 foot seas daytime and 20 mph from the east and 3 foot seas nighttime. Just a quick reminder that you still have time to take advantage of the 25 percent discount on trips on the Galaxy Wave to La Ceiba. Tickets can be bought this month for future trips!

Low tides are 12:30 p.m. and 12:30 a.m. Have a great Friday!
