La Nina Weakenning — Spring Ahead!!

Hi everybody! As we begin to leave behind our Florida Winter, the Spring storm season will soon be upon us. Atmospheric conditions have been in a La Nina state for most of the winter. This is why we have been having such cool temperatures and dry weather conditions. La Nina is a cooling of the tropical Pacific ocean waters. This cooling is gradually dissipating and most models are pointing to this condition to end by Spring. ENSO Neutral conditions are forecast to be in place during our summer storm season. The exact time of the transition is not fully known but should be completed by July. What this could mean for us is a continuation of very dry and below normal temps for the next couple of months. After the transition to neutral, our weather will become more seasonal with more precipitation and a better chance for hurricane development. As you know, neutral conditions arte never good during the peak storm season. There are many other factors that must come into play also besides the ENSO. These include but are not limited to location of High pressure ridges, water temperatures and SAL (the amount of African dust in the atmosphere). SAL often will help impede the formation of hurricanes because the sand in the atmosphere tends to dry out the air and this helps keep storms at bay.

We will have to watch these developments as they unfold over the next couple of months.

Please remember to “Spring Ahead” this Sunday. Daylight savings time again starts this weekend. Be sure to set your clocks an hour ahead before retireing Saturday night.

The next newsletter will be published next month or sooner if conditions warrant.
