Mainly fair weather conditions prevail across the basin under the influence of two middle level highs supporting dry air subsidence. Scattered showers are in the SW basin associated with the E Pacific monsoon trough. Otherwise, gentle to locally moderate winds are across the region due to a weak pressure gradient. Swell associated with tropical cyclone Teddy as well as generated by a cold front currently extending along 24N W of 65W will impact much of the Atlantic passages beginning on Wed.
