NO STORM WARNING. No storm warning is currently active for the forecast area.

A weak pressure gradient prevails over the tropical Atlantic and the Guianas marine domain, with the North Atlantic Subtropical High centered well to the northeast (1028 mb, near the Azores) and a stalling frontal trough over the western Atlantic beyond 55W exerting little influence on the forecast area. The ITCZ/monsoon trough axis is analyzed near 55W between 6.1N and 8.1N (NHC estimate 8.1N; GFS low-level convergence estimate 6.1N), placing the main convective axis only about 2.1° (roughly 126 nautical miles) north of the Suriname coastline — markedly closer than typical for mid-August. The axis extends from near 10N60W through 8N55W to 11N54W, then northeastward as a monsoon trough toward 20N16W. Two weak surface lows, 1006 mb near 78W01N and 1007 mb near 60W02N, support a modest pressure gradient over the central Caribbean but have limited direct bearing on the Guianas coast. Two tropical waves are tracked across the basin: one with axis near 61W (south of 20N) moving west around 10 knots, and a second near 42W extending 02N to 18N moving west 10 to 15 knots; per the latest NHC Tropical Weather Discussion neither wave currently carries significant organized convection, though scattered moderate convection is noted between 11N and 17N near the eastern wave axis.

North of 08N: ENE to E winds, moderate (Bft 3–4), with scattered to numerous showers and thunderstorms concentrated close to the ITCZ axis between 06N and 08N — i.e. immediately adjacent to the coastal waters — producing sudden near-gale gusts (locally Bft 7) with strong downdrafts in the stronger cells. Away from the ITCZ band, north toward 12–15N, conditions are more settled with isolated showers only. South of 08N (coastal waters): ENE to E by day with a sea-breeze veer toward ESE near the coast by mid-afternoon; partly cloudy with an elevated risk of afternoon and evening thunderstorms along the coastal sea-breeze front, given the unusually close ITCZ, becoming ESE to E overnight as convective activity shifts onshore.
