Subtropical Storm Andrea Forecast Discussion Number 1
2019-05-21 00:34:34| National Hurricane Center (Atlantic)
Issued at 630 PM AST Mon May 20 2019 000 WTNT41 KNHC 202234 TCDAT1 Subtropical Storm Andrea Special Discussion Number 1 NWS National Hurricane Center Miami FL AL012019 630 PM AST Mon May 20 2019 Satellite and aircraft data indicate that the area of low pressure that the National Hurricane Center has been monitoring to the southwest of Bermuda has developed into a subtropical storm. The Air Force Hurricane Hunters have recently exited the cyclone and found that the system has developed a well-defined center and has a minimum pressure of about 1006 mb. The maximum adjusted flight-level and surface SFMR winds support an intensity of about 35 kt. The cyclone is considered subtropical at this time because it is interacting with an upper-level low pressure system to its west, has a relatively large radius of maximum wind, and its overall appearance in satellite images. Based on satellite and aircraft fixes today, the initial motion of Andrea is estimated to be northward at 12 kt as it has been moving in the flow between a subtropical ridge to its east and a mid- to upper-level low to its west. The models show Andrea slowing down and gradually turning to the northeast on Tuesday and eastward by Tuesday night as it moves on the northern periphery of the ridge. Andrea could strengthen slightly through early Tuesday while it remains in a fairly moist and unstable atmosphere. However, after that time, gradual weakening should commence due to less favorable conditions, and all of the reliable models show Andrea opening into a trough and becoming absorbed by a cold front on Wednesday. The NHC official track forecast lies near the middle of the guidance envelope.

SUMMARY OF 630 PM AST...2230 UTC...INFORMATION ---------------------------------------------- LOCATION...28.8N 68.7W ABOUT 335 MI...540 KM SW OF BERMUDA MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...N OR 350 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...1006 MB...29.71 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. Interests in Bermuda should monitor the progress of this system. DISCUSSION AND OUTLOOK ---------------------- At 630 PM AST (2230 UTC), the center of Subtropical Storm Andrea was located near latitude 28.8 North, longitude 68.7 West. The storm is moving toward the north near 14 mph (22 km/h). A decrease in forward speed and a turn to the northeast is expected on Tuesday, followed by an eastward motion by Tuesday night. On the forecast track, the center of Andrea is expected to remain southwest or south of Bermuda during the next day or two. Data from an Air Force Reserve Hurricane Hunter plane indicate that the maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Slight strengthening is possible overnight. Weakening should begin late Tuesday, and Andrea is expected to dissipate on Wednesday. Winds of 40 mph extend outward up to 70 miles (110 km) northeast of the center. The Air Force Hurricane Hunters measured a minimum central pressure of 1006 mb (29.71 inches). HAZARDS AFFECTING LAND ---------------------- None NEXT ADVISORY ------------- Next complete advisory at 1100 PM AST. $$ Forecaster Cangialosi
