First light visible imagery shows cold convective cloud tops near the estimated center that also appear to be rotating cyclonically. While we haven't had any recent C-band scatterometer passes near the center of this system, a recent KU-band scatterometer showed plenty of non-rain contaminated winds to help confirm that a closed circulation exists. Subjective Dvorak classifications were up to T2.0/30-kt from TAFB and T1.5/25-kt from SAB. A recently arriving SSMIS pass at 1159 UTC also showed a well-defined curve band wrapping at least 75 percent around the northwestern side of the system. All these data indicate a new tropical depression has formed, and the initial intensity will be set at 30 kt this advisory. Currently the depression is moving westward at 275/6 kt. A large deep-layer ridge is situated north of the cyclone which should steer it on a general westward to west-southwestward heading over the next day or so. Afterwards, the larger circulation of Tropical Storm Frank is expected to get close enough to initiate binary interaction with the depression. The net result of this interaction is that the depression is likely to bend even more southward than the larger-scale steering flow would initially suggest, and there is some chance that Frank may capture the smaller depression. For now, the track forecast keeps Frank and TD Eight-E separate, showing a very slow west-northwestward motion towards the end of the forecast period. This track forecast is roughly follows the TVCE aid early on, but is slower later in the forecast period due to uncertainty with interaction with Frank to the east. This initial track forecast is of low confidence. The intensity forecast is also challenging and strongly related to how much interaction this depression has with the larger circulation of Frank. Assuming the depression remains separate, environmental conditions only appear marginally favorable for intensification in the short-term, with moderate easterly vertical wind shear, and plenty of nearby dry air that could get ingested into the small circulation at any time. For these reasons, the intensity forecast only shows modest intensification over the next 24-48 hours and caps the storm at 40 kt thereafter due to uncertainty in its future evolution near Frank. This is roughly in line with the latest SHIPS guidance, but is lower than the HCCA and other consensus intensity aids which are biased by the larger and stronger wind field of Frank later on in the forecast.

Issued at 1000 AM CDT Wed Jul 27 2022 536 WTPZ42 KNHC 271452 TCDEP2 Tropical Storm Frank Discussion Number 6 NWS National Hurricane Center Miami FL EP072022 1000 AM CDT Wed Jul 27 2022 Frank continues to feel the effects of about 20 kt of northeasterly vertical wind shear, with the low-level center remaining just northeast of the current convective burst. Various subjective and objective satellite intensity estimates are in the 35-40 kt range, and these have changed little since the last advisory. Based on this, the initial intensity remains 35 kt. The global models suggest that the current shear should ease over the next 12-24 h and allow Frank to gradually strengthen. Between 24-72 h, the shear is forecast to become light while the cyclone is over 28-29C sea surface temperatures, and this environment could allow for steady, and possible rapid, intensification. The forecast peak intensity of 75 kt is unchanged from the previous forecast due to uncertainty as to whether Frank will have a good enough structure to rapidly intensify. However, this is in the middle of the intensity guidance and could be conservative. After 72 h, Frank should move over decreasing sea surface temperatures, and this should cause weakening. Frank is wobbling between a westward and west-northwestward motion with the current motion of 285/9. A subtropical ridge to the north of the cyclone should continue to steer Frank generally westward for the next 36 h or so, followed by a west-northwestward motion from 36-72 h. After that time, the cyclone is expected to moved more northwestward toward a break in the ridge caused by by a mid- to upper-level trough developing over the Pacific west of California. The new official forecast rack is similar to the previous track through 60 h, and then is nudged a little to the north of the previous forecast in response to a northward shift of the guidance. The new forecast is close to or a little south of the various consensus models. It should be noted that Frank and the newly-formed Tropical Depression Eight-E are likely to come close enough to one another to interact. The global models suggest that Frank will be the larger and dominant system during this interaction, and that the depression will have only minor impacts on the track and intensity of Frank.

South of Baja California peninsula:
Shower activity associated with a low pressure area located several
hundred miles south-southwest of the southern tip of the Baja
California peninsula has become better organized since this morning.
Additional development of this system is possible during the next
day or so while it remains near stationary, and a tropical
depression could form during this time. After that, interaction
with Tropical Storm Frank to the east of this system is expected to
prevent further development.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.

Issued at 1000 AM CDT Tue Jul 26 2022 000 WTPZ42 KNHC 261451 TCDEP2 Tropical Storm Frank Discussion Number 2 NWS National Hurricane Center Miami FL EP072022 1000 AM CDT Tue Jul 26 2022 Satellite imagery this morning depicts a sheared bursting pattern associated with the tropical cyclone. An overnight convective burst obscured the low-level circulation center, but first-light visible imagery now shows the vortex mostly exposed east of the colder convective cloud tops. This structure can also be seen from the last couple SSMIS microwave passes near the center and is characteristic of environmental vertical wind shear (VWS) diagnosed between 15-20 knots from the northeast. Subjective Dvorak intensity estimates from TAFB and SAB were T2.5/35-kt and T2.0/30-kt respectively, while the latest UW-CIMSS ADT estimate was at T2.5/35-kt. The initial intensity has been raised to 35-kt this advisory, upgrading the tropical depression to tropical storm Frank. Northeasterly VWS between 15-20 kt is expected to continue over the next 48 hours, and will likely limit significant intensification in the short-term as the shear promotes misalignment between the low-level and mid-level centers. The latest intensity forecast only shows slow intensification in the short-term. Afterwards, this shear is expected to decrease, while the storm will remain over warm sea-surface temperatures near 29C through 96 hours. However, the current shear may also help broaden Frank's wind field as convection is favored outside of the radius of maximum wind, as suggested by the latest ECMWF run. These structural changes could limit more robust intensification later in the forecast despite the more favorable environment. For now, the latest NHC forecast still peaks Frank as a category 1 hurricane towards end of the forecast period. This forecast is on the lower end of the intensity guidance envelope, close to the LGEM model, and is somewhat lower than the consensus aids HCCA and IVCN. The tropical storm is moving generally westward at 280/9-kt. The track guidance is in fairly good agreement that this motion and heading will continue as a mid-level ridge extends westward to the north of Frank over the next 2-3 days. Towards the end of the forecast, the ridge overhead will begin to gradually weaken, and will likely allow a larger Frank to begin gaining more latitude. One complicating factor in the track forecast is the possibility of some weak binary interaction with another low-level circulation located to Frank's northwest, where the net interaction may help impart a bit more northerly heading to Frank's track between 72-96 hours. For now, the track forecast continues to favor a blend of the GFS and ECMWF forecast (GFEX) and is quite close to the previous forecast track.
