A satellite shows the dust plume over the Caribbean and a second one emerging off the coast of Africa on Tuesday. (NOAA) Conditions associated with the Madden-Julian Oscillation are currently not favorable for lifting motion or storminess over the Atlantic. (NOAA/CPC) Rising motion is favored to approach the tropical Atlantic by August, with more rising motion and slightly enhanced odds of tropical cyclone development. (NOAA/CPC) A gentle swing toward La Niña during the fall could enhance hurricane activity over the Atlantic. This NOAA schematic depicts typical conditions associated with a La Niña weather pattern. (NOAA) In a La Niña, high pressure generally results in weaker winds aloft over the tropical west Atlantic. If upper-level winds are too strong, they can tear apart a developing storm. That’s why the weak winds […]
