We are again seeing an eye-like feature on microwave., though it is considerably more defined in the northern half of the storm.

Edit:
Ok, 10am NHC update is out, and they are also seeing this eye-like feature on microwave. They are also saying that conditions should be favorable for strengthening later today.
