link to a great satellite shot....notice the few specs of red...typically in a hurricane this particular satellite shot has a ring of red around the core....
definitely something to watch for....for the last 24 hour no red (colder cloudtops) have been noted.....a sign of strengthening would be a sustained flareup represented in the shot as brighter colors.
unfortunately..this will be one of the last shot from the satellite (or an other weather satellites) for a couple hours as the nightly "eclipse" takes place (earth between sats and sun..no power) so we cant monitor this latest possible flareup.
