I suppose we'll see the major impact of the heatwave in next weeks injection #s. Heat indicies today 105 in Central Park, 110F in Philly and 115 in DC...and tomorrow a little worse.
The disturbance approaching the Carribbean has just been yellow circled by the National Hurricane Center...they are giving it a 20% chance of developing into a tropical storm during the next 48 hours (they don't indicate what they think will happen after that). I'll update as things change, especially if it appears that a storm will enter into or form in the Gulf of mexico.
