Tropical Storm Chantal Forecast Discussion Number 5
Issued at 500 PM EDT Sat Jul 05 2025
398 WTNT43 KNHC 052033 TCDAT3 Tropical Storm Chantal Discussion Number 5 NWS National Hurricane Center Miami FL AL032025 500 PM EDT Sat Jul 05 2025 The satellite presentation of Chantal has not changed much throughout the day with convective banding and a concentrated area of deep convection located over the eastern semicircle of the storm. The Air Force Reserve reconnaissance aircraft that investigated Chantal through midday found a peak 850-mb flight-level wind of 51 kt which supported the increase in winds to 40 kt on the 1800 UTC intermediate advisory. With no significant change in structure since that time, the intensity remains 40 kt for this advisory. Another Air Force Reserve reconnaissance aircraft is scheduled to investigate the system this evening. The moderate shear that has been affecting Chantal is forecast to decrease some this evening, however drier mid-level air appears to be being entrained into the western part of the circulation. Therefore only slight strengthening is predicted before Chantal reaches the coast of South Carolina overnight or early Sunday. After landfall, steady weakening should occur and the system is expected to open up into a trough by Monday. Recent fixes show that Chantal has begun moving a little faster toward the north with an initial motion estimate of 360/6. The track guidance suggests that the storm will turn north- northwestward between a mid- to upper-level low over the Gulf and a narrow mid-level ridge over the western Atlantic. A turn to the northeast is expected after landfall as Chantal becomes more embedded within the low- to mid-level flow around the west side of the ridge. The NHC track forecast lies close to the TVCA multi-model consensus, which is close to the previous NHC forecast. Chantal is expected to remain asymmetric with its strongest winds and rainfall to the right of the landfall location. Key Messages: 1. Tropical storm conditions are expected in the warning area beginning this evening and continuing through Sunday morning. 2. Heavy rainfall across portions of the Carolinas will cause flash flooding concerns through Monday, especially in urban areas. 3. Chantal is expected to bring life-threatening surf and rip currents along the coast from northeastern Florida to the Mid-Atlantic states during the next day or so. Beach goers should heed the advice of lifeguards and local officials.

Tropical Storm Chantal Forecast Discussion Number 4
Issued at 1100 AM EDT Sat Jul 05 2025
000 WTNT43 KNHC 051455 TCDAT3 Tropical Storm Chantal Discussion Number 4 NWS National Hurricane Center Miami FL AL032025 1100 AM EDT Sat Jul 05 2025 Satellite images suggest that Chantal has been organizing and gaining strength. The storm is still asymmetric though, with most of the associated showers and thunderstorms located near and to the east of the center. The Air Force Hurricane Hunters are currently investigating the system and have found that the pressure has dropped to 1007 mb. The plane has yet to sample the area of strong thunderstorms, where the highest winds are likely occurring. The initial intensity is set at 35 kt for now. The outer rainbands are beginning to reach portions of South and North Carolina, and conditions along the coast within the watch and warning areas are expected to continue to deteriorate throughout the day. Chantal has barely moved since last night, but a motion to the north-northwest is expected to begin soon. The main steering features appear to be a mid- to upper-level low over the Gulf and a narrow mid-level ridge across the mid-Atlantic region. The flow between these features should cause Chantal to move inland over South Carolina Sunday morning. It should be noted that center reformations are possible, which could cause some erratic motion. After landfall, a turn to the northeast is expected when the storm moves on the western side of the ridge. The NHC track forecast lies close to the previous one, and the latest HCCA and Google Deep Mind solutions. Additional strengthening seems likely in the short term as Chantal is expected to remain over warm water and move into a lower wind shear environment. In addition, the shear direction is expected to shift from southwesterly to southerly, which is more conducive for strengthening. The NHC intensity forecast is a little higher than the previous one, and in line with the latest HMON, HAFS-A, and HAFS-B guidance. After landfall, steady weakening is expected until the system dissipates in 48 to 60 hours. Chantal is expected to remain a lopsided system during the next day or so. Therefore, the strongest winds are anticipated to occur to the right of the landfall location. Key Messages: 1. Tropical storm conditions are expected in the warning area beginning this evening and continuing through Sunday morning. 2. Heavy rainfall across the coastal Carolinas will cause some flash flooding through Monday. Isolated to scattered flash flooding could occur within more urbanized areas in the coastal plain of the Carolinas. 3. Chantal is expected to bring life-threatening surf and rip currents along the coast from northeastern Florida to the Mid-Atlantic states during the next couple of days. Beach goers should heed the advice of lifeguards and local officials.

Tropical Depression Three Forecast Discussion Number 3
Issued at 500 AM EDT Sat Jul 05 2025
930 WTNT43 KNHC 050852 TCDAT3 Tropical Depression Three Discussion Number 3 NWS National Hurricane Center Miami FL AL032025 500 AM EDT Sat Jul 05 2025 The depression has been showing signs of organization overnight, with a significant burst of deep convection currently seen on GOES-19 infrared imagery on the eastern semicircle of the tropical cyclone. However, the center of the tropical depression appears to still be displaced westward from this burst, estimated to be on the edge of the larger cirrus plume. An earlier scatterometer pass received just after the prior advisory indicated the peak winds were up to 32 kt, so the depression may be close to tropical storm strength. For now though, the initial intensity is being held at 30 kt blending the lower subjective and higher objective Dvorak intensity estimates. An Air Force Reserve Reconnaissance mission is scheduled to sample the system later this morning and should provide more in-situ information about the cyclone later today. The depression continues to meander this morning, with my best guess at an estimated motion to be at 030/2-kt. The track forecast in the short-term is somewhat tricky, since the lopsided nature of the convection with the system suggests that there could be some center reformations/relocations to the north and/or east later today. Thereafter, the main steering features are a mid-to-upper level low over the northeastern Gulf, and a narrow mid-level ridge to the northeast of the depression. Their combined influence should result in a general north-northwestward track over the next 24-36 h. The track guidance this cycle has come in further east this run, somewhat in response to the adjusted initial position. The NHC track forecast has been shifted eastward in response to this shift in the guidance, favoring the deterministic ECMWF (EMXI) over the GFS (AVNI), but it is not as far west as some of the track aids, including the Google Deep Mind ensemble mean (GDMI) and European deterministic AIFS (EAII). The vertical wind shear over the system is probably the most unfavorable it will be as the system remains over the warm Gulf Stream waters. In fact, both the GFS and ECMWF-based SHIPS guidance shows the current southwesterly shear decreasing from 20 kt currently to more like 10-15 kt over the next 24 h. However, there is some dry mid-level air lurking to east that might temper more robust intensification. All things considered, assuming the depression becomes better aligned vertically, at least some modest intensification should occur, and the latest NHC intensity forecast still shows a peak intensity of 40 kt before the system moves inland over South Carolina on Sunday Morning. While this forecast is on the upper end of the interpolated intensity guidance, the raw output from both the 00z HAFS-A and HAFS-B have a peak intensity a little above that value in 24 h. After landfall, the cyclone should weaken and is forecast to become post-tropical in about 48 h. It is a little unclear if the circulation will open up into a trough by early next week or if some remnant circulation will move back offshore beyond that time period. For now, the NHC forecast will stick to the former solution showing dissipation by 60 h. Given the eastward shift in the guidance this cycle, the Tropical Storm Watch has been extended eastward to Cape Fear, North Carolina this advisory. Key Messages: 1. Tropical storm conditions are possible in the watch area beginning this evening and continuing through Sunday morning. 2. Heavy rainfall across the coastal Carolinas will cause some flash flooding concerns from Tropical Depression Three from today through Monday. Isolated to scattered flash flooding could occur within more urbanized areas along the coastal plain of the Carolinas. 3. The system is expected to bring rough surf and rip currents to much of southeastern United States north of northeastern Florida during the next couple of days.
