The National Hurricane Center reported at 11:00 a.m. EDT on Tuesday, August 26, that what was once Tropical Storm Julio, is now a remnant low pressure system over the Gulf of California.

The Hurricane Center noted in their discussion that "Julio lacks enough organized deep convection to be considered a tropical cyclone, and is therefore degenerating into a remnant Low (pressure area). This remnant low is expected to dissipate in a day or so."

At that time, Julio's center was located near latitude 28.4 north, longitude 112.4 west or about 95 miles west-northwest of Guaymas, Mexico. The depression is moving toward the north near 5 mph and Julio's remnants are expected to continue drifting northward for the next day or so. Maximum sustained winds are near 30 mph and the estimated minimum central pressure is 1005 millibars.

The remnants of Julio are expected to produce additional 1 to 2 inches of rain over northwestern Mexico with isolated maximum storm totals of up to 4 inches possible. Moisture and showers associated with Julio will spread over portions of the southwestern United States, bringing up to 2 inches of rainfall.

This visible satellite image of Julio was created by data from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite. It was captured on August 25, 20:29 UTC (4:29 p.m. EDT).

Tropical Storm Julio is producing heavy rainfall over central portions of the Baja California peninsula today, Monday, August 25.

At 5:00 a.m. PDT, the center of tropical storm Julio was estimated near latitude 26.3 north and longitude 112.0 west or about 45 miles (70 km) west-northwest of Loreto, Mexico. Julio is moving toward the north-northwest near 15 mph (24 km/hr). Maximum sustained winds are near 40 mph (65 km/hr) with higher gusts. He is expected to weaken and become a tropical depression later today. Estimated minimum central pressure is 1002 millibars.

Meanwhile, Julio will continue to move across the central Baja California peninsula today and into the Gulf of California tonight and Tuesday.

Julio is expected to produce total rainfall accumulations of 3 to 6 inches over portions of the central and southern Baja California Peninsula, with isolated maximum amounts of 10 inches possible.

This satellite image of Julio was created by data from the Atmospheric Infrared Sounder (AIRS) on NASA's Aqua satellite.

It shows the temperature of Julio's cloud tops on August 25, 9:29 UTC (5:29 a.m. EDT). The lowest temperatures (in purple) are associated with high, cold cloud tops that make up Julio's center. There are large areas of strong convection (rising air and rainfall) shown here in purple. Where there are no clouds the AIRS instrument reads the infrared signal from the surface of the Earth (over both land and water), revealing warmer temperatures (red).
