Tropical Storm Dalila intensified over the Eastern North Pacific Ocean southwest of Mexico on Saturday morning. More thunderstorms formed near the center of Dalila’s circulation. More thunderstorms also developed in bands revolving around the center of Tropical Storm Dalila. Storms near the center of Dalila generated upper level divergence that pumped mass away from the tropical storm. The removal of mass caused the surface pressure to decrease.
The circulation around Tropical Storm Dalila was large. Winds to tropical storm force extended out 230 miles (370 km) from the center of Dalila’s circulation.
Tropical Storm Dalila will move through an environment favorable for intensification during the next 24 hours. Dalila will move over water where where the Sea Surface Temperatures are near 27°C.
