Tropical Depression BONNIE Forecast Discussion Number 24

2016-06-02 16:35:05| National Hurricane Center (Atlantic)

Issued at 1100 AM EDT THU JUN 02 2016 000 WTNT42 KNHC 021434 TCDAT2 TROPICAL DEPRESSION BONNIE DISCUSSION NUMBER 24 NWS NATIONAL HURRICANE CENTER MIAMI FL AL022016 1100 AM EDT THU JUN 02 2016 Satellite imagery and coastal radar data indicate that the low pressure area that was formerly Bonnie has developed persistent organized convection near the center. Based on this, the system is again being designated as a tropical depression. The initial intensity of 25 kt and central pressure of 1009 mb are based on surface data near the center, along with a satellite intensity estimate of 25 kt from TAFB. The initial motion estimate is 055/5. Bonnie is moving along the southern edge of the mid-latitude westerlies, and the cyclone should move generally east-northeastward to eastward with a gradual increase in forward speed during the next couple of days. The track forecast follows that of the various consensus models, which are tightly clustered. The center of Bonnie will be moving over warm Gulf Stream waters for the next 12-24 hours while the vertical wind shear is light. Thus, the intensity forecast calls for modest strengthening during that time. After that, increasing shear and sea surface temperatures below 24C should cause Bonnie to again degenerate to a remnant low, with the system dissipating by 72 hours.

Issued at 1100 AM EDT THU JUN 02 2016 000 WTNT32 KNHC 021434 TCPAT2 BULLETIN TROPICAL DEPRESSION BONNIE ADVISORY NUMBER 24 NWS NATIONAL HURRICANE CENTER MIAMI FL AL022016 1100 AM EDT THU JUN 02 2016 ...BONNIE RE-DEVELOPS INTO A TROPICAL DEPRESSION... ...POTENTIAL FOR ADDITIONAL HEAVY RAINFALL CONTINUES OVER COASTAL EASTERN NORTH CAROLINA... SUMMARY OF 1100 AM EDT...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...35.1N 75.1W ABOUT 25 MI...40 KM ESE OF CAPE HATTERAS NORTH CAROLINA MAXIMUM SUSTAINED WINDS...30 MPH...45 KM/H PRESENT MOVEMENT...NE OR 55 DEGREES AT 7 MPH...11 KM/H MINIMUM CENTRAL PRESSURE...1009 MB...29.80 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 AM EDT (1500 UTC), the center of Tropical Depression Bonnie was located near latitude 35.1 North, longitude 75.1 West. The depression is moving toward the northeast near 7 mph (11 km/h). A turn toward the east-northeast and an increase in forward speed are expected later today. On the forecast track, the center of Bonnie should move away from the coast of North Carolina this afternoon and tonight. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Some slight strengthening is possible during the next 24 hours. After that time, Bonnie is expected to again become a post-tropical low. The estimated minimum central pressure is 1009 mb (29.80 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Gusty winds may occur over portions of the eastern North Carolina coast this afternoon, including the Pamlico Sound. RAINFALL: Bonnie is expected to produce additional rainfall accumulations of 1 to 3 inches over the Outer Banks of North Carolina through Thursday evening. Isolated maximum amounts of 5 inches are possible. This rain will likely produce flooding over already saturated ground. STORM SURGE: Localized coastal flooding and dangerous surf is possible along portions of the North Carolina coast, including the Outer Banks. For information specific to your area, please see products issued by your local National Weather Service office. NEXT ADVISORY ------------- Next complete advisory at 500 PM EDT. $$ Forecaster Beven
