Andy, the sun and heating of the day isnt a contribute to strengthning of a system. Alot think that but its not true. Tropical system like the high increase in humidity during the night time hours and higher duew points. Usually convection decreases in the afternoon hours. Doesnt mean though this or any system cant get stronger during the day but just generally heating of the day and sun doesnt casue strengthning, Ill udate more moreon this system early this afternoon, looks like my Cuba landfall of near 81-82W might be just a tad to the right asa general movement to the W last night took place interacting with the Ridge to its N.
