# Low-Pressure System May Develop Over Bay of Bengal Between November 11 and 15 - Link: https://www.weather.lk/low-pressure-system-may-develop-over-bay-of-bengal-between-november-11-and-15/ - Published: 2026-11-08T21:53:32+05:30 - Author: WeatherLK ### **What Does This Mean for Sri Lanka?** The latest bulletin does not indicate any expected depression formation over the Bay of Bengal or Arabian Sea during the coming days. However, the presence of convective cloud activity over parts of the surrounding seas indicates that unsettled weather conditions may continue in some areas. It is important to note that the absence of expected cyclogenesis does not necessarily mean that Sri Lanka will experience dry weather. Localised showers and thunderstorms can still occur due to other atmospheric conditions. A developing weather system over the Bay of Bengal could bring unsettled weather conditions in the coming days, prompting the Department of Meteorology to issue a special weather bulletin for multi-day fishing boats operating in deep-sea areas of the Bay of Bengal. According to the Department of Meteorology, there is a possibility of a low-level atmospheric disturbance developing over the southeastern Bay of Bengal and adjoining Andaman Sea around November 11, 2026. Under the influence of this disturbance, a low-pressure area is likely to form over the southeastern Bay of Bengal around November 13. Meteorologists have also indicated a low probability that the system could further intensify into a depression over the southwestern Bay of Bengal around November 15. **Advisory for Fishing and Naval Communities** The Department of Meteorology has advised naval and fishing communities operating in the affected sea areas to remain vigilant and pay close attention to future weather forecasts and special bulletins. Multi-day fishing boat operators are particularly encouraged to monitor official weather updates before making decisions about their activities at sea. The bulletin was issued at 4.15 p.m. on November 6, 2026, and remains valid from November 11 to November 15, 2026. The public and maritime communities are advised to follow updates issued by the Department of Meteorology as the weather system develops. The situation may change, and further information will be provided through official weather bulletins. ![](https://scontent.fcmb10-1.fna.fbcdn.net/v/t39.99422-6/888033440_2297428067465551_3933318065187389712_n. png?stp=dst-jpg_tt6&cstp=mx1448x2048&ctp=s590x590&_nc_cat=104&_nc_map=urlgen_bucketless& ccb=1-7&_nc_sid=127cfc&_nc_ohc=XhmIoNFXVTUQ7kNvwFy-6FU&_nc_oc=AdriMCHqpdK-grel0BftOgFEySFAR6EtFSOhlYcOh- DUMNX7hVM2v35n8TIo1f2pqd1eOIAg4nH78mVT9Ebhlo3x&_nc_zt=14&_nc_ht=scontent.fcmb10- 1.fna&_nc_gid=f5ku8PZjkNjLJdqrYkIQCw&_nc_ss=7b2a8&oh=00_AQQ8qoWRdEqaP9S1xVCb_6AL_2ASojVHmPwO- 7KpYuscQw&oe=6AF3B63F) ### **Bay of Bengal: No Cyclogenesis Expected** According to the latest outlook, scattered low and medium-level clouds with embedded moderate to intense convective activity are present over the central and southern Bay of Bengal, the Andaman Sea, the Gulf of Martaban and the Tenasserim Coast. Meanwhile, scattered low and medium clouds with isolated weak convective activity are observed over the North Bay of Bengal. Despite this cloud activity, the probability of cyclogenesis (the formation of a depression) remains NIL throughout the next 168 hours. ### **Arabian Sea: Cyclonic Circulation Persists Near Comorin Area** Over the Arabian Sea, a cyclonic circulation that was observed over the southeastern Arabian Sea, off the southern Kerala coast, yesterday had shifted towards the Comorin area and its neighbourhood. The circulation was located over this region at 5:30 AM and continued to persist in the same area at 8:30 AM on 08 November 2026. Scattered to broken low and medium-level clouds, accompanied by intense to very intense convective activity, are observed over the southern Arabian Sea, Lakshadweep Islands, Maldives and Comorin area. Additionally, scattered low and medium clouds with moderate to intense convective activity are present over parts of the central Arabian Sea, while isolated weak convective activity is observed over the northwestern Arabian Sea. However, the outlook indicates that the probability of depression formation over the Arabian Sea also remains NIL during the next 168 hours.
