Tropical Storm Felicia Forecast Discussion Number 2
2021-07-14 16:50:42| National Hurricane Center (East Pacific)
Issued at 900 AM MDT Wed Jul 14 2021 000 WTPZ41 KNHC 141450 TCDEP1 Tropical Storm Felicia Discussion Number 2 NWS National Hurricane Center Miami FL EP062021 900 AM MDT Wed Jul 14 2021 Recent satellite data indicate that the tropical cyclone has continued to organize this morning. An AMSR2 microwave pass around 0900 UTC revealed a well-defined banding feature that wrapped more than half-way around the center and early-light visible images show a developing CDO with the center located beneath the eastern portion of the cold cloud tops. Based on Dvorak T-numbers of 3.0 and 2.5 from TAFB and SAB, respectively, the initial intensity was increased to 40 kt on a Tropical Cyclone Update issued at 1315 UTC. With the continued increase in organization, the advisory intensity has been raised to 45 kt. Felicia is located over warm SSTs and in an area of low vertical wind shear. Given the recent development of a small inner-core, it seems likely that Felicia will continue to strengthen during the next couple of days. The only caveat appears to be nearby dry air that could get entrained into the circulation of the relatively small tropical cyclone and cause some disruptions in the intensification process. Although most of the intensity guidance is not extremely bullish and the rapid intensification probabilities are not particularly high, the NHC forecast predicts steady strengthening and brings Felicia to hurricane status within 24 hours. The NHC wind speed forecast is in best agreement with the HFIP corrected consensus model, which is at the upper-end of the guidance. The tropical storm is moving west-northwestward or 285/13 kt. A mid-level ridge to the north of Felicia should steer the storm west-northwestward to westward during the next 12-24 h. After that time, the orientation of the ridge shifts slightly which is expected to cause Felicia to turn west-southwestward with some decrease in forward speed during the middle portion of the forecast period. The dynamical model guidance is in reasonably good agreement, and the NHC forecast lies near the TVCE consensus aid. The guidance envelope did shift a little southward from the previous cycle, and the new NHC forecast has been modified accordingly.

SUMMARY OF 900 AM MDT...1500 UTC...INFORMATION ---------------------------------------------- LOCATION...14.3N 114.1W ABOUT 655 MI...1055 KM SSW OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...50 MPH...85 KM/H PRESENT MOVEMENT...WNW OR 290 DEGREES AT 15 MPH...24 KM/H MINIMUM CENTRAL PRESSURE...1002 MB...29.59 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 900 AM MDT (1500 UTC), the center of Tropical Storm Felicia was located near latitude 14.3 North, longitude 114.1 West. Felicia is moving toward the west-northwest near 15 mph (24 km/h) and this motion is expected to continue with a decrease in forward speed through Thursday. A turn toward the west is expected by Thursday night, and a west or west-southwestward motion is forecast Friday and Saturday. Maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Additional strengthening is likely and Felicia is forecast to become a hurricane tonight or Thursday. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- None.
