Track of Hurricane Carlos (04E) - July 13th, 2009

On July 9th, showers and thunderstorms associated with an area of disturbed weather located about 900 miles south of the southern tip of Baja California became more concentrated around a developing low level centre.

In the early hours of July 10th, the system was designated as Tropical Depression04E, and the NHC commenced advisories. This stage of the system’s development can be observed in the main and enhanced images.

Around 2:00 p.m. PDT, the system strengthened into Tropical Storm Carlos. On July 11th, Tropical Storm Carlos strengthened into a minimal Category 1 hurricane. It also developed a small eye feature, based on satellite presentation.

However, by the morning of July 12th, the National Hurricane Center noted that the small eye like feature had disappeared. Overnight on July 11th through the morning of July 12th, the structure of Carlos became disorganized for unknown reasons.

Deep convection contracted to a small region around the center of circulation and the overall size of the storm diminished. In the early afternoon hours, the continued degeneration of the system led to its downgrade to tropical storm status. Forecasters from the National Hurricane Center stated that the reasons why Carlos has weakened so much are still “a bit of a mystery”.

The animated imagery shows the more recent movements of the system. At 8:00 PM PDT (0300 UTC), the center of Tropical Storm Carlos was located about 1230 miles (1985 km) southwest of the southern tip of Baja California. The system is moving toward the west near 12 mph (19 km/hr), and this general motion is expected to continue over the next couple of days.

Maximum sustained winds are near 60 mph (95 km/hr) with higher gusts. Some strengthening is forecast during the next day or two. Tropical storm force winds extend outward up to 60 miles (95 km) from the center. Estimated minimum central pressure is 994 mb (29.35 inches).
