How Arnab developed
October 26 — Tropical storm recorded
At 00:00 UTC, the observation recorded TWO as a tropical storm over the Bay of Bengal, at 16°N, 89.1°E. Sustained winds were 65 km/h, gusts were 75 km/h, and central pressure was 1002 mb. This is the only reading on file, so it does not establish when the system first reached tropical-storm strength.
October 26 — Strengthens to a category 1 cyclone.
At 06:00 UTC, Arnab's classification had risen from tropical storm to category 1 cyclone. Sustained winds reached 120 km/h, up from 65 km/h six hours earlier, while gusts increased from 75 km/h to 138 km/h. Pressure fell from 1,002 mb to 986 mb.
October 27 — Strengthens to a category 2 cyclone.
At 00:00 UTC on October 27, Arnab reached category 2 with winds of 167 km/h, gusts of 192 km/h and pressure of 968 mb. Six hours earlier, the reading showed category 1 winds of 148 km/h and pressure of 972 mb. The latest centre was 249 km southeast of Visakhapatnam in the Bay of Bengal.
October 27 — Strengthens to a category 4 cyclone.
At 06:00 UTC on October 27, ARNAB’s classification rises from category 2 to category 4. The reading records winds of 213 km/h, gusts of 245 km/h and pressure of 947 mb, compared with 167 km/h winds and 968 mb six hours earlier. The centre is 178 km SSE of Visakhapatnam.
October 27 — Weakens to a category 3 cyclone.
At 12:00 UTC, Arnab was a category 4 cyclone with 222 km/h winds and 940 mb pressure. By 18:00 UTC, the reading showed a category 3 cyclone, 185 km/h winds and 958 mb pressure. The 37 km/h wind decrease and 18 mb pressure rise mark the change in intensity.
October 28 — Weakens to a category 1 cyclone.
At 00:00 UTC on October 28, Arnab was over Bhimavaram, India, with sustained winds of 130 km/h, gusts of 150 km/h and pressure of 977 mb. The previous reading, six hours earlier, showed a category 3 cyclone with 185 km/h winds and 958 mb pressure. The latest reading records a category 1 cyclone.
October 28 — Weakens to tropical-storm strength.
At 06:00 UTC, Arnab had sustained winds of 102 km/h and gusts of 117 km/h, with pressure at 988 mb. The reading marked a drop from category 1 strength six hours earlier, when winds were 130 km/h and pressure was 977 mb. The latest position was 33 km ESE of Bhimavaram, India.
October 29 — Weakens to a tropical depression.
At 06:00 UTC on October 29, Arnab's maximum sustained winds were 46 km/h, down from 74 km/h at the previous reading at 12:00 UTC on October 28. The classification fell from tropical-storm strength to tropical depression, while pressure rose from 992 mb to 1,005 mb.
How Arnab is behaving
The record contains one observation, so it cannot show a pressure trend or whether the storm is organizing or weakening. The 1002 mb value is the central pressure, a measure of atmospheric pressure near the storm’s center. The reading pairs that pressure with sustained winds of 65 km/h and gusts of 75 km/h; a gust is a brief increase above the sustained wind. The storm’s motion is listed as 275° at 11 km/h. A bearing is a direction measured clockwise from north, making 275° just north of due west. One point cannot establish how steadily the storm has moved.
How to track Arnab
Turn on the tropical storm tracks layer in RainViewer to view the recorded path. Each point marks the storm’s position and category at that moment. The track colours show tropical depression in cyan, tropical storm in blue, category 1 in yellow, category 2 in amber, category 3 in orange, category 4 in red and category 5 in dark red. TWO’s recorded point is blue because the reading classifies it as a tropical storm.
The record currently contains one point in the Bay of Bengal, so it shows TWO’s observed position but not a sequence of past positions. The reading also records 65 km/h winds, 1002 mb pressure and motion at 11 km/h on a 275° bearing. Open RainViewer on Google Play or the App Store to follow the track as readings are added. For official warnings, check your national weather service.
How October cyclones fit the north Indian Ocean season
October falls in the post-monsoon cyclone season of the north Indian Ocean, which runs broadly from October through December. Cyclones can form when warm ocean water supplies moisture and energy, while atmospheric conditions allow thunderstorms to organize around a rotating circulation. Those are general ingredients, not measurements of TWO. This reading gives no information about where the system formed or about the ocean and atmospheric conditions around it.
Past north Indian Ocean storms show that cyclone strength and outcomes vary. Cyclone Fani in 2019 reached category 4-equivalent strength on the Saffir–Simpson scale and made landfall. Cyclone Amphan in 2020 reached category 5-equivalent strength on the same scale and also made landfall. These category equivalents describe wind intensity; the regional classification system uses different storm categories.
Storm FAQ
What does a 275° storm direction mean?
A bearing is measured clockwise from north, so 275° points just north of due west. TWO’s recorded motion is westward at 11 km/h.
Why are tropical cyclones given names?
Names give storms short, distinct labels that make them easier to identify in communication and records. TWO is the identifier used for this system in the available record; the reading does not give it a personal storm name.
What is the difference between sustained wind and a gust?
Sustained wind describes the ongoing wind speed, while a gust is a brief, higher-speed burst. TWO’s reading lists 65 km/h sustained winds and 75 km/h gusts.
