TD 20E Strengthens to Tropical Storm Ramon

Former Tropical Depression Twenty-E strengthened to Tropical Storm Ramon over the Eastern North Pacific Ocean southwest of Baja California on Friday evening. At 10:00 p.m. EST on Friday the center of Tropical Storm Ramon was located at latitude 13.8°N and longitude 122.6°W which put it about 1040 miles (1675 km) southwest of the southern tip of Baja California. Ramon was moving toward the north at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1005 mb.

Former Tropical Depression Twenty-E exhibited more organization on Friday evening and the U.S. National Hurricane Center upgraded it to Tropical Storm Ramon. The distribution of thunderstorms around Tropical Storm Ramon was still asymmetrical. Most of the thunderstorms were occurring in bands in the eastern side of Ramon’s circulation. Bands in the western side of the circulation consisted primarily of showers and lower clouds. The distribution of wind speeds was also asymmetrical, Winds to tropical storm force extended out 35 miles (55 km) in the eastern side of Ramon’s circulation. The winds in the western side of Tropical Storm Ramon were blowing at less than tropical storm force.

Tropical Storm Ramon will move through an environment somewhat favorable for intensification during the next 12 hours. Ramon will move over water where the Sea Surface Temperatures are near 27°C. It will move under the eastern part of an upper level trough over the Eastern North Pacific. The upper level trough will produce southwesterly winds that will blow toward the top of Ramon’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but it may not be strong enough to prevent some further intensification during the next 12 hours. Tropical Storm Ramon could intensify a little during the first half of Saturday. The upper level winds are forecast to get stronger later on Saturday. Stronger upper level winds would cause the vertical wind shear to increase. More wind shear would cause Tropical Storm Ramon to start to weaken.

Tropical Storm Ramon will move around the western part of a high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer Ramon slowly toward the north during the next 24 hours. On its anticipated track, Tropical Storm Ramon will remain far to the southwest of Baja California.
