A bomb cyclone weather forecast warns of a low-pressure system that deepens extremely fast – pressure drops at least 24 hectopascals in 24 hours at mid-latitudes – bringing destructive winds, heavy rain and coastal storm surge. The Bureau of Meteorology issues specific warnings for these events, often days ahead.

What does a bomb cyclone forecast mean for Australia?

In Australia, bomb cyclones are most common along the east and south-east coasts, especially during autumn and winter. They form when a cold front interacts with warm ocean currents, creating a rapid pressure drop. The forecast will highlight damaging wind gusts, abnormally high tides and prolonged rainfall that can cause flash flooding. The BOM’s severe weather warnings are your primary alert. You should check the BOM weather Australia page for the latest updates.

How to track a bomb cyclone with BOM tools

Use the bom cyclone tracking map to see the system’s position and forecast path. For a wider view, the bom cyclone tracking map australia satellite shows cloud patterns and intensity. If you need real-time movement, the bom cyclone tracking map live updates every hour. The bom cyclone 7 day forecast gives the extended outlook, but remember bomb cyclones can intensify quickly – always check a cyclone warning today before making plans. Combine this with the weather radar to track rain bands and wind shifts.

DefinitionPressure drop of ≥24 hPa in 24 hours at 60°S (adjusted for latitude)
Typical impactsDamaging winds >90 km/h, heavy rain >100 mm in 12 hours, coastal erosion
Warning lead timeBOM usually issues warnings 48–72 hours before peak intensity
Australian hotspotsNSW coast, Victoria’s Gippsland, southern Queensland, and Tasmania
How is a bomb cyclone different from a normal low?

A normal low deepens gradually over days. A bomb cyclone’s pressure drops at least twice as fast, producing much stronger winds and heavier rain in a shorter period. The rapid change makes forecasting and preparation more urgent.

What should I do if a bomb cyclone is forecast?

Secure loose outdoor items, move vehicles under cover, and avoid coastal areas during high tide. Monitor the weather warning page and have an emergency kit ready. Stay indoors during the worst winds.

Can bomb cyclones be predicted accurately?

Yes, modern models can forecast bomb cyclones 3–5 days in advance, but exact timing and intensity may shift. The BOM updates its bom cyclone tracking map every few hours as new data arrives, so check frequently.
