Thinking Ida is in the midst of an RI episode right now. Very intense convective burst overhead which corresponds to an intense curved inner band (formative eyewall?) on recon data. We'll have a hurricane before the sun sets tonight.
Grace's pressure is 992mb on the extrap just offshore of the Yucatan. Also considerably lower than the NHC current estimate of 999. Surface winds are stronger too with 55kts in the NE quad, where as the NHC has winds pegged at 45kts.
