Three subtropical disturbances remain present across the mid-latitudes of the Atlantic Ocean as follows...

The remnant surface low of disturbance Invest 97-L has moved northward away from Bermuda ahead of the 1006 mb frontal depression that has emerged from the SE US (supported by the upper trough currently emerging from the eastern US). Meanwhile the disturbance's former overhead upper vortex has shifted ea...

Upper winds remain favorable in the eastern tropical Atlantic with tropical upper ridging (marked by blue H in the lower right of the atmospheric features chart below). The tropical wave which has recently emerged from western Africa however has lost shower and thunderstorm activity due to dry Saharan air seen in the lower-right of the thermodynamics chart below....and upper winds in the eastern tropical Atlantic will...

Upper winds in the eastern tropical Atlantic are favorable with tropical upper ridging (marked by blue H in the lower right of the atmospheric features chart below). A tropical wave southwest of the Cape Verde Islands has seen an increase in showers and thunderstorms below this upper ridge...but is not expected to develop while leaving the favorable upper ridge in the next 24 hours. Another tropical wave about to emer...

Tropical low pressure Invest 96-L midway between the Lesser Antilles and Cape Verde Islands is experiencing westerly shear from a southern fracture of a north-central Atlantic upper trough more than previously forecast (marked by blue-dashed line north of 96-L in the atmospheric features chart below). Therefore this system is no longer likely to develop and I have cancelled it as a special feature on this blog.

Tropical low pressure Invest 96-L midway between the Lesser Antilles and Cape Verde Islands has become stationary rather than moving west. And with the surface low likely to be quasi-stationary for another 96 hours...it will become distant from the unfavorable upper vortex moving into the Lesser Antilles and potentially tap into more favorable upper winds as tropical upper ridging expands in the wake of the upper vo...
