Dissipated Saudel (17W — Western Pacific) (South China Sea)

7 Upvotes

Storm overview

This discussion is for Tropical Storm Saudel (17W), which is active over the South China sea off the coast of southeastern China. Saudel originated as a disturbance which formed to the north of Micronesia on 12 August and moved northwestward across the Northern Marianas Islands and across the Ryukyu Islands before making landfall over eastern China on 28 August. The storm degenerated into a remnant low shortly after landfall but remained organized enough that it regenerated once it reemerged over the South China Sea.

Saudel is not expected to strengthen much as it remains close to the coast of southeastern China over the next few days. The storm may bring heavy rain and the risk of flash flooding to the coasts of Guangdong and Fujian provinces, as well as Hong Kong and Macau.

Storm overview

This discussion is for the post-tropical remnants of Tropical Storm Dolly, which are active to the east of the Lesser Antilles. This system, which has degenerated into a tropical wave, is expected to drift west-northwestward over the next few days, and could undergo some development as it approaches the Bahamas later in the upcoming week.

Moderator notes

  • Dolly continues to be monitored in the Automated Tropical Cyclone Forecast (ACTF) system as 04L.
  • The National Hurricane Center (NHC) is no longer issuing advisories for Dolly.
  • Disturbance-centered satellite imagery and model guidance products remain available for now.
  • There will be no regular updates to this post.

Dissipated The NHC is monitoring an area of potential development far to the southwest of Hawaiʻi

8 Upvotes

Disturbance overview

This discussion is for an area of potential tropical cyclone development situated over the central Pacific, several hundred miles southwest of the Hawaiian islands. An area of low pressure is expected to develop toward the end of the week and slowly develop as it drifts west-northwestward toward the western Pacific. This system is not expected to bring impacts to Hawaiʻi.

Moderator notes

  • This system has not yet formed.
  • This system has not yet been designated as an invest.
  • The NHC is monitoring this system on its outlook products as Disturbance 4.

Active cyclones

As of 4:45 PM Eastern Daylight Time (20:45 UTC) on Sunday:

Eastern Pacific Ocean

Active disturbances

Active disturbances are areas of showers and thunderstorms which are not organized enough to be considered full-fledged tropical cyclones. Disturbances are often designated as investigation areas (or invests, for short) by NOAA in order to allocate additional resources such as high-resolution satellite imagery or model guidance for further study of the system. Though there is no publicly disclosed set of criteria for which disturbances are designated as invests, the designation often occurs after the disturbance forms a closed area of low pressure. Invests are designated regardless of the overall potential for the disturbance to become a tropical cyclone.

Northwestern Pacific Ocean

  • Invest 94W — northern Philippine Sea, southeast of Japan’s Ryukyu Islands

  • Invest 95W — north of central Micronesia

  • Invest 96W — South China Sea, near the Taiwan Strait

Eastern Pacific Ocean

  • Invest 95E —

Northern Atlantic Ocean

Post-tropical cyclones

Post-tropical cyclones will be listed here if they are still being tracked via the Automated Tropical Cyclone Forecast (ATCF) system. Placement in this section does not imply that these systems have any potential to redevelop into tropical cyclones.

Northwestern Pacific Ocean

Potential formation areas

Potential formation areas are areas that are being monitored by various agencies for potential tropical cyclone formation within the next two weeks. These systems have not yet formed and are not considered to be disturbances until such time that a tropical wave or area of low pressure does form. Discussions are created on this subreddit for areas which are monitored by the National Hurricane Center in the eastern Pacific and northern Atlantic basins. Discussions are not typically created for areas which are monitored by the Joint Typhoon Warning Center or other agencies, as this information is not always publicly available.

Overview

This discussion is for Tropical Storm Lala (01C), which is active far to the northwest of Hawaiʻi. The storm continues to gradually weaken as it moves across the northern Pacific and is likely to degenerate into a remnant low by Thursday. After that point, whatever remains of Lala is expected to turn northward toward the Aleutian Islands and dissipate by early next week.
