Still a Cat 5 from yesterday (October 7, 2014) and pressure still holding 900mb’s. Heading for southern Japan with a projected path to weaken and turn NE. Could this one break the…
by WeatherFlow meteorologist Shea Gibson. As a quick recap, The Intertropical Convergence Zone where tropical storms form, or the “ITCZ”, is heavily impacted by the Saharan Air Layer (or “SAL”), which is a dust layer off the western African coast along the lower and mid levels of the atmosphere. This dry, dusty more stable air rides just over the…
…by WeatherFlow meteorologist Shea Gibson. This is a follow up from the Blog done on 9/29/14 questioning the possible arrival: http://blog.weatherflow.com/post-summer-frontal-approach-to-the-se-region-first-marine-layering-event/ Friday, October 3 we had an approaching strong cold front from the west. Most everything lined up very similar to last year’s November 1, 2013 frontal approach; however, it appears that this year started earlier with…
by WeatherFlow meteorologist Shea Gibson Last year we saw our first recorded marine layering event during the summer-to-fall transition as water temps started to cool, which kept winds down along the immediate beaches 5-10kts lower than what computer models were mostly in agreement with. 16-20kt predictions turned out to be 10-14kts with many UP’s and…
By WeatherFlow meteorologist Shea Gibson For Coastal South Carolina: As we get into the cooler months of fall and winter, we start to see more NE events unfold along the SE Region as colder High pressures to the north wedge down behind cold fronts that push through. For NE winds, as a cardinal direction we…

by WeatherFlow meteorologist Shea Gibson We are currently seeing a very seasonal summer setup with vast blocking subtropical ridge known as the “Bermuda-Azores High pressure” over the North Atlantic Ocean. As it assumes its typical 1024mb status and keeps more of a near-Bermuda presence, we encounter periods of strengthened Sea Breezes along the SE Region…
