Ana is looking pretty ragged as we head into the diurnal minimum. Late afternoon is the time of the day when convection is the lowest, because the sun heats up the upper atmosphere more than the sea surface, causing the difference in temperature between the surface and the upper atmosphere to be the lowest. Early morning is the diurnal maximum, that's when the upper atmosphere cools more than the sea surface, allowing more differential between the surface and upper atmosphere.
Ana's had an up and down day in terms of intensity. But she's at her weakest point in a couple of days according to the ADT estimate. I don't know how much she'll regain in strength tonight, but she's got a ways to go to become a hurricane.
Latest GFS run is nudged a little further south. I think that direction continues to be welcome news to the Big Island. Not sure how this all looks for Honolulu.
