Tropical Storm Howard Forecast Discussion Number 9

3 years ago
Issued at 900 AM MDT Mon Aug 08 2022 000 WTPZ44 KNHC 081438 TCDEP4 Tropical Storm Howard Discussion Number 9 NWS National Hurricane Center Miami FL EP092022 900 AM MDT Mon Aug 08 2022 Compared to yesterday at this time, Howard has become a much better organized tropical cyclone. After the previous advisory, we received an AMSR-2 microwave pass valid at 0844 UTC, which showed a nearly closed cyan ring at 36 GHz, suggesting a low-level eye feature had developed. More recently, 1-minute GOES-18 interleave satellite imagery is occasionally depicting a banding-type eye signature with colder cloud tops beginning to wrap around this feature. Subjective Dvorak intensity estimates from SAB and TAFB were both T3.5/55 kt at 1200 UTC, which supports raising the intensity to 55 kt this advisory. Howard is still moving northwestward at 315/11 kt. The track guidance remains is good agreement that this northwestward motion will continue for the next 24 hours as Howard remains steered by a mid-level ridge to its northeast. Starting tomorrow, the storm should gradually turn west-northwestward as the cyclone becomes more vertically shallow and is increasingly steered by the low-level trade wind flow. The guidance has shifted ever so slightly north of the previous track forecast, and the latest NHC track was nudged in that direction, remaining close to the consensus aids TVCE and HCCA. Howard has another 12-18 hours over greater than 26 C sea surface temperatures (SSTs) in a low shear environment. Given the improvement in the inner core structure and higher initial intensity, the latest NHC forecast was raised quite a bit from the previous advisory and now shows Howard becoming a hurricane later today. After 24 hours, the storm will be moving over rapidly cooling SSTs as the atmospheric environment becomes more stable with shear also increasing. Thus, steady weakening is expected and the latest intensity forecast still makes Howard post-tropical in 60 hours. This forecast is higher than the intensity guidance over the first day, but falls back in line with the consensus aids after that time period.

Tropical Depression Nine-E Forecast Discussion Number 5

Issued at 900 AM MDT Sun Aug 07 2022 000 WTPZ44 KNHC 071441 TCDEP4 Tropical Depression Nine-E Discussion Number 5 NWS National Hurricane Center Miami FL EP092022 900 AM MDT Sun Aug 07 2022 The depression remains disheveled this morning, with the center of the system still partially exposed to the southwest of the deepest convective activity. This structure is primarily due to dry air being imported to the center by moderate southwesterly vertical wind shear (VWS). Subjective Dvorak intensity estimates were T2.5/35 kt from TAFB, T2.0/30 kt from SAB, while the latest objective estimate from UW-CIMSS ADT was T2.5/35 kt. Given the lackluster satellite presentation, the initial intensity was held at 30 kt for this advisory. The depression is now moving northwest as a slightly slower pace, estimated at 315/10 kt. A mid-level ridge located northeast of the system is expected to steer it generally northwestward over the next few days. One interesting note in the immediate future is there is a weakness in this ridge to the north, partially related to an upper-level trough currently shearing the depression. If the system is able to become better aligned vertically, this could lead to a rightward shift in the short-term track. The NHC track forecast accounts for this possibility by being located on the right side of the track guidance envelope over the next 12-36 hours. This track is just a bit northeast of the previous one, though it blends back towards the consensus aids by the end of the forecast, when the system will likely be steered by the low-level trade wind flow. A weak upper-level trough located northwest of the depression is the primary feature maintaining southwesterly VWS over the system. Over the next day or so, both the GFS and ECMWF suggest this feature should decay and shift southwest, perhaps related to convection building up-shear around the depression while helping to align its low and mid-level centers. Should this process occur, intensification still appears possible. One alternate solution is that convective outflow is not able to displace the upper-level low and some amount of shear is maintained over the system. For now, the latest NHC intensity forecast will maintain a peak of 45 kt in 36-48 hours, right around the time the system will be crossing the 26 C sea surface temperature (SST) isotherm. After that time, weakening is expected over even cooler SSTs and a more stable environment. The system is still expected to become a post-tropical remnant low at the end of the forecast period. This intensity forecast is on the high side of the guidance envelope overall, but is close to the latest HCCA consensus aid.

Tropical Depression Nine-E Forecast Discussion Number 1

Issued at 1000 AM CDT Sat Aug 06 2022 000 WTPZ44 KNHC 061441 TCDEP4 Tropical Depression Nine-E Discussion Number 1 NWS National Hurricane Center Miami FL EP092022 1000 AM CDT Sat Aug 06 2022 The low pressure system that NHC has been monitoring off the coast of southwestern Mexico has continued to show increased signs of organization this morning. A 0857 UTC AMSR2 microwave pass suggests its circulation has become better defined, and satellite imagery shows evidence of some curved convective banding mainly to the east of its estimated low-level position. Additionally, the subjective Dvorak classifications from TAFB and SAB were T2.0 and T1.5, respectively. Since the system now meets the criteria of a tropical cyclone, advisories are being initiated on this system as a 30-kt tropical depression. The center is located near the western edge of the convective mass, likely due to the 10-15 kt of westerly shear that the cyclone is experiencing this morning. Although weak to moderate shear may continue to affect the system during the next couple of days, the majority of the guidance suggests that warm SSTs and sufficient mid-level moisture should allow for at least gradual strengthening through early next week. This trend is reflected in the NHC forecast, which calls for the depression to become a tropical storm by tonight and continue intensifying to near hurricane strength by Tuesday. Then, the system is forecast to move into a drier, more stable environment over decreasing SSTs, which should induce a weakening trend through the middle of next week. The estimated initial motion of the depression is northwestward, or 305/11 kt. A distant low- to mid-level ridge over the southern U.S. should steer the cyclone northwestward to west-northwestward over the next few days, keeping it well offshore of the coast of southwestern Mexico. Although there is reasonably good agreement in the early part of the forecast period, there is above-average spread in the track guidance on days 3-5. Stronger model solutions like the GFS and HWRF lie on the northern end of the guidance envelope, while the weaker ECMWF and UKMET solutions are much further south. The official NHC forecast generally follows the multi-model consensus aids, but lies a bit north of HCCA and TVCE at later forecast times.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Fri Aug 5 2022

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

Offshore of Southern Mexico:
A broad low pressure area located offshore of the coast of southern
Mexico is producing a large area of disorganized shower activity.
Environmental conditions appear conducive for development of this
system, and a tropical depression is likely to form during the next
couple of days. The system is forecast to move generally
west-northwestward at 10 to 15 mph over the weekend and into early
next week, remaining well offshore of the coast of southwestern
Mexico.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

Well Southeast of the Main Hawaiian Islands:
An area of low pressure is forecast to form over the far western
portion of the eastern Pacific basin by this weekend. Environmental
conditions could allow for some gradual development of this system,
and a tropical depression could form early next week while it moves
westward toward and into the central Pacific basin.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.
