Good morning Bay Islands. Our photo of the day comes from Bob Jacobs in Palmetto Bay.
It’s been plenty hot. The high at the airport yesterday 91 (33C) with a heat index of 110 (43C). Over the next few days there isn’t any relief in sight, with mostly sunny skies and very little to no chance for rain. This time of year there is hope of a return of some squalls

Here’s the US GFS forecast for the next two weeks. From now until about the 20th it keeps us dry. As we get toward the end of the month it’s trying to pull in more rain from the Caribbean, but I will warn that long range forecasts are not very reliable and there is nothing major that would change our weather pattern right now. The only thing cooling us off are our continuing strong easterly trade winds that also show no sign of calming.

I’ve received some inquiries about the cause of major floods in San Pedro Sula on June 12. Here is the satellite from that day, and you can indeed see a storm develop in the evening hours of that day. The highest rain reading I could find for that day was 2 inches (the airport south of the city reported no rain at all). But for the previous week, the city had been averaging about half an inch a day. We are in a low pressure system called the Central American Gyre that has been causing tropical storms on the Pacific side of Honduras and SPS has been picking up storms on the periphery. My guess is that those previous rains had cause drainage to be clogged with garbage and two, maybe three inches in places, was enough to cause severe flooding in areas of poor drainage.
