On the forecast track, the center of Matthew will pass north of the Guajira Peninsula this afternoon and tonight and remain over the central Caribbean Sea through early Sunday. Data from a NOAA Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 120 mph (195 km/h) with higher gusts.
