Tropical Storm Frank Forecast Discussion Number 10

3 years 1 month ago
Issued at 900 AM MDT Thu Jul 28 2022 564 WTPZ42 KNHC 281440 TCDEP2 Tropical Storm Frank Discussion Number 10 NWS National Hurricane Center Miami FL EP072022 900 AM MDT Thu Jul 28 2022 Conventional satellite imagery this morning suggests that the northeasterly shear over Frank is diminishing, with some cirrus outflow developing in the northeastern quadrant. However, SSM/IS microwave overpasses at 1144 and 1234 UTC show that the storm has not yet become better organized, as the center is still located to the northeast of the main convective bands. Various satellite intensity estimates range from 35-55 kt, and given the unchanged organization the initial intensity is held at 45 kt. A further reduction in the shear appears likely later today, which along with sea surface temperatures of 28-29C, should allow steady to possible rapid strengthening through the 60 h point. The new intensity forecast continues to call for a peak intensity of 90 kt, and this is at the upper edge of the intensity guidance. After 60 h, while the shear is forecast to remain light, the cyclone should move over steadily decreasing SSTs, reaching 21C water by 120 h. This should cause a steady to rapid weakening. This part of the intensity forecast has been adjusted downward and it lies near the intensity consensus aids. Frank continues to move westward with the initial motion 280/11 kt. The track forecast reasoning is again unchanged from the previous advisory. A turn toward the west-northwest is expected during the next 12-24 h, followed by a northwestward motion as the cyclone heads for a break in the subtropical ridge produced by mid- to upper-level troughing over the northeastern Pacific. The track guidance remains in good agreement, but it has again shifted just a little to the north after about 36 h. Thus, the new track forecast is nudged a little northward during that time. It should be noted that Frank and Tropical Storm Georgette are likely to come close enough to one another to interact. The global models still suggest that Frank will be the larger and dominant system during this interaction, and that Georgette will have only minor impacts on the track and intensity of Frank.

Tropical Depression Eight-E Forecast Discussion Number 1

3 years 1 month ago
Issued at 900 AM MDT Wed Jul 27 2022 000 WTPZ43 KNHC 271459 TCDEP3 Tropical Depression Eight-E Discussion Number 1 NWS National Hurricane Center Miami FL EP082022 900 AM MDT Wed Jul 27 2022 The area of low pressure we have been monitoring more than 500 miles southwest of the Baja California peninsula has continued to become better organized this morning. 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.

Tropical Storm Frank Forecast Discussion Number 6

3 years 1 month ago
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.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Tue Jul 26 2022

For the eastern North Pacific...east of 140 degrees west longitude:

Active Systems:
The National Hurricane Center is issuing advisories on recently
upgraded Tropical Storm Frank, located several hundred miles south
of the southern coast of Mexico.

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.

Public Advisories on Tropical Storm Frank are issued under WMO
