Peter stays as a tropical storm with the maximum winds of 60 mph.Look at figure #1 at the link above and read why they didn't upgrade Peter as a hurricane despite that band feature eye that it had for a few hours.

Observations in Tropical Storm Peter primarily consist of satellite-based Dvorak technique intensity estimates from the Tropical Analysis and Forecast Branch (TAFB), the Satellite Analysis Branch (SAB) and the U.S. Air Force Weather Agency (AFWA). Visible satellite imagery and microwave data suggested the development of an eye feature that was best defined around 1515 UTC 9 December. In general, the presence of an eye feature on satellite imagery would correspond to a tropical cyclone of hurricane intensity. In fact, the 3-h average objective Dvorak T-number was 4.0 during that period. However, the eye feature was transient and by 1800 UTC it had begun to dissipate. The best estimate of the maximum winds associated with Peter is 60 knots.
