Hurricane Blas Forecast Discussion Number 10

3 years 1 month ago
Issued at 1000 AM CDT Thu Jun 16 2022 000 WTPZ42 KNHC 161437 TCDEP2 Hurricane Blas Discussion Number 10 NWS National Hurricane Center Miami FL EP022022 1000 AM CDT Thu Jun 16 2022 The satellite presentation of Blas in geostationary imagery has not changed much this morning with the center embedded within the northern portion of the central dense overcast. Recent microwave imagery, however, shows that there has been some additional degradation of the inner-core due to moderate east-northeasterly shear. There is a bit more uncertainty than normal in the initial intensity of the hurricane as the subjective Dvorak estimates are on the higher end at 77 and 90 kt, while objective satellite estimates from the ADT and SATCON are lower at 70 and 64 kt, respectively. The advisory intensity is kept near a consensus of these estimates at 75 kt. Although the shear is forecast to relax slightly during the next 12-24 hours, the recent degradation of the inner core will likely prevent any further intensification. Therefore, little change in strength is anticipated through tomorrow morning. By 36 hours, Blas is forecast to cross the 26 degree Celsius isotherm which should commence the weakening process. Steady weakening is then anticipated during the remainder of the forecast period while Blas moves into less favorable thermodynamic conditions, and the cyclone is forecast to degenerate into a remnant low by day 4. The NHC intensity prediction is in best agreement with the LGEM model and ICON consensus aid. The initial motion estimate is west-northwestward or 290/7 kt. A mid-level ridge to the north of the hurricane should continue to steer the cyclone west-northwestward with some increase in forward speed over the next 48-72 hours. After that time, a weaker and more shallow Blas is likely to turn westward or west-southwestward within the lower-level tradewind flow. There is very little cross-track spread among the various dynamical models, but there is some along-track or speed differences with the HWRF, HMON, and GFS much faster than the ECMWF. The new NHC track forecast is a little faster than the previous advisory, closer to the latest HCCA and TVCE consensus aids, but additional adjustments could be required in subsequent advisories. While Blas is expected to remain off the coast of Mexico, its associated swells are affecting portions of the coast of southwestern Mexico and are expected to spread to portions of the southern Baja California peninsula by late Friday. These swells are likely to cause dangerous surf and rip current conditions in those areas through the weekend.

Hurricane Blas Forecast Discussion Number 6

3 years 1 month ago
Issued at 1000 AM CDT Wed Jun 15 2022 305 WTPZ42 KNHC 151457 TCDEP2 Hurricane Blas Discussion Number 6 NWS National Hurricane Center Miami FL EP022022 1000 AM CDT Wed Jun 15 2022 Since the prior advisory, the structure of Blas has continued to improve on both conventional and microwave satellite imagery. In fact, several SSMIS microwave passes indicate that Blas is developing an inner core, with at least a banding mid-level eye feature showing up on the 89-GHz channel. The latest 1200 UTC subjective Dvorak estimates were T3.5/55 kt from TAFB and T4.0/65 kt from SAB. In addition, the most recent objective Dvorak estimates from UW-CIMSS have been quickly increasing with the latest estimate at T4.3/72 kt. A blend of the aforementioned data yields 65 kt for the advisory initial intensity, making Blas a hurricane. The center of Blas may have relocated a bit further south into the large overnight convective burst, but its mean motion this morning has continued a pronounced left turn, estimated at 290/4 kt. A continued west-northwest motion with some acceleration is anticipated over the next several days as the mid-level ridge poleward of the storm continues to build in and extend westward ahead of Blas. Towards the end of the forecast, Blas is expected to become a shallow system, resulting in a slowing westward motion as the low-level flow exerts greater influence. The latest forecast track has been adjusted a bit south in the short-term based on the adjusted initial position , but ends up just north of the previous forecast by the end of the period, close to the center of the track guidance envelope. The most recent microwave images suggest that Blas is developing an inner core, which would likely support further intensification today as the system remains over warm (28-29 C) sea surface temperatures (SSTs) embedded in sufficently high mid-level moisture. A possible complicating factor is that both the GFS- and ECMWF-based SHIPS guidance indicates easterly shear increasing to 20-25 kt over the next 24-36 h. Assuming this does not play a major inhibiting factor, the latest NHC forecast indicates continued intensification and peaks Blas as category 2 hurricane in 24 h. After 36 h, Blas will be crossing a sharp SST gradient, moving over sub 26 C waters by 60 h. For this reason, weakening is anticipated to begin by Friday. At the end of the forecast period, Blas is likely to lose its deep-convective activity and become a shallow low-level vortex. While Blas is expected to remain off the coast of Mexico, its associated swells are expected to affect portions of the coast of southwestern Mexico beginning today and continuing through the end of the week.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Wed Jun 15 2022

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

The National Hurricane Center is issuing advisories on Tropical
Storm Blas, located a few hundred miles south of the southwest coast
of Mexico.

Off the coast of Central America:
A large area of showers and thunderstorms off the coast of Guatemala
and El Salvador are associated with a trough of low pressure.
Gradual development of this system is possible while it drifts
erratically, and it could become a tropical depression during the
next couple of days. Environmental conditions are forecast to
become less conducive for development by this weekend. Regardless of
development, locally heavy rains are possible across portions of El
Salvador, Guatemala, and southeastern Mexico during the next several
days.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

Tropical Storm Blas Forecast Discussion Number 2

3 years 1 month ago
Issued at 1000 AM CDT Tue Jun 14 2022 752 WTPZ42 KNHC 141458 TCDEP2 Tropical Storm Blas Discussion Number 2 NWS National Hurricane Center Miami FL EP022022 1000 AM CDT Tue Jun 14 2022 Satellite images indicate that the tropical cyclone southwest of Mexico continues to become better organized, with plenty of banding in the eastern semicircle and increased central deep convection. Dvorak estmates have increased to 35-45 kt, and the initial wind speed is raised to 40 kt, making this system the second tropical storm of the season. The environment near Blas looks conducive for further intensification during the next couple of days, with very warm waters and generally light shear. However, increased northeasterly shear is likely to begin on Thursday due to a building upper-level anticyclone over Mexico. Model guidance is higher than the last cycle, mostly due to the initial wind speed, and the NHC intensity forecast matches that trend. Weakening should commence by the end of the week due to stronger shear and cooler waters. Blas is drifting northward, caught in an area of light steering beneath a distant mid-tropospheric low over northern Mexico. The tropical cyclone should move little today and then start moving to the west-northwest at a faster pace due to the low moving out and a ridge building over Mexico. This motion should take the system gradually away from southwestern Mexico later in the week. Similar to the last cycle, although there is some spread in the models, especially in terms of forward speed, they generally agree on the overall scenario. This track forecast lies near the various consensus aids, a bit north of the last NHC track forecast. Even though the system is forecast to remain well off the coast of Mexico, the associated swells are expected to affect portions of the coast of southwestern Mexico in a day or so.
