2 African Waves Under Watch as Atlantic Hits Peak Hurricane Season

For climate and resilience professionals, Aug. 7-8 updates from meteorologist Mike Buresh map the Atlantic's seasonal transition with operational precision: two African waves under NHC watch, an upper-level low near Jacksonville producing non-tropical coastal hazards, and steering patterns that could favor recurvature away from the U.S. East Coast. The real story is not whether the basin will produce storms, but how shear and the Bermuda High will shape their tracks as peak season approaches.

Despite a syndicated headline that calls it the 'last day of the Atlantic hurricane season,' the Aug. 7-8 briefings from Jacksonville meteorologist Mike Buresh actually capture the Atlantic basin entering its seasonal peak. The Atlantic hurricane season runs from June 1 through Nov. 30, and the early-August wave train is exactly what forecasters expect as the basin approaches its most active stretch. The updates, carried by WOKV and Action News Jax, blend immediate Southeast U.S. impacts with a longer-range look at two African easterly waves.

The real story is not whether the basin will produce storms, but how shear and the Bermuda High will shape their tracks as peak season approaches.

An upper-level low east and northeast of Florida has been ingesting moisture from a weak tropical wave, enhancing disorganized showers and thunderstorms from Florida to the Carolinas. The system was increasing rip current risk from Georgia through the Carolinas as of Saturday, Aug. 8, and was forecast to drift north then northeast through Sunday and Monday. Forecasters explicitly said no significant tropical development is expected at the surface. As the disturbance moves away, rainfall coverage is expected to decrease over Northeast Florida and Southeast Georgia. This part of the story is operational rather than tropical-cyclone news: a reminder that even non-tropical upper-level features can produce dangerous coastal conditions.

At the same time, the National Hurricane Center had highlighted two African waves on Saturday afternoon. The first was over the Eastern Atlantic and moving steadily west. Its lower-latitude track would take it toward or over the Caribbean by late in the upcoming week, but wind shear looks prohibitive for much development, so no significant impacts are anticipated on approach. The second wave was expected to come off the coast of Africa about Tuesday. A more north/northwest track gives it a better chance to thrive at least somewhat. However, the expected break in the Bermuda High—one center far to the east-northeast over the Atlantic and a second building over the Southern/Southeast U.S.—would create a weakness that allows curvature to the north and northeast well east of the U.S. and the Bahamas. Buresh noted it seems unlikely at this point that this wave would complete a full trans-Atlantic track.

The climatological markers in the briefings anchor the current activity. The average date of the third named storm is Aug. 3, and the first Atlantic hurricane averages Aug. 11. In other words, the basin is right on schedule rather than anomalously active, even if the headline suggests otherwise. The wave train cycling up is a signal of the seasonal shift toward peak hurricane season, when African easterly waves become primary seedlings for tropical cyclones. Shear, not sea surface temperature, is the immediate limiting factor in the forecast window: conditions may look favorable over the Eastern/Central Atlantic from the middle to end of next week, but strengthening shear near the West Atlantic could turn hostile.

The commentary also references velocity potential anomalies—rising air in green lines equates to an uptick in overall convection and more favorable conditions for tropical development, while brown lines indicate sinking air and less conducive conditions. This diagnostic is part of the broader atmospheric circulation signal that forecasters use to predict whether waves have room to develop. In the current setup, the favorable convection over the African wave train is offset by hostile shear across the western Atlantic, meaning development may be delayed or steered into the open ocean. That tension between favorable and unfavorable factors is characteristic of the August transition period.
