Narelle is not forecast to directly “hit” Perth as a tropical cyclone, but Perth is expected to feel its effects mainly as heavy rain and windy conditions over the coming weekend rather than a direct cyclone landfall.

Latest timing for Perth

  • Forecasts indicate Narelle will be a severe category 3–4 system near the Pilbara and North West Cape on Friday, then weaken as it tracks further south down the WA coast.
  • More recent guidance suggests the cyclone’s core will stay well north of Perth, with the center likely to cross the coast somewhere around Exmouth–Carnarvon–Shark Bay, then move inland and weaken.
  • For Perth itself, current outlooks talk about impacts (rain and wind) over Friday and Saturday, not a precise “eye over the city” landfall time.

What Perth is likely to experience

  • Heavy rain bands and a “drenching” are expected, with around 50 mm of rain possible between Friday and Saturday if current tracks hold.
  • Forecasters are flagging the chance of flooding in Perth and parts of the Gascoyne and Pilbara, with rivers and creeks rising from Thursday onward as the system moves south.
  • Strong, gusty winds and squally showers are likely, but the most destructive cyclone-force winds are expected much further north near Exmouth, Carnarvon and surrounding districts.

Why there’s no exact “hit time”

  • Cyclones often change speed and direction slightly as they interact with land and cooler waters, which is why agencies talk about “this weekend” or “from Friday onward” instead of giving to-the-hour Perth timings several days ahead.
  • Forecast tracks have already shifted: early model runs suggested a more direct threat to Perth, while newer forecasts keep the core circulation further north, with Perth on the rainy, windy fringe.

Quick reality check (forum-style view)

In current public weather coverage and news reports, “when will cyclone Narelle hit Perth” is being answered more like “Perth is in for a soaking and possible flooding over Friday–Saturday, but the actual cyclone center probably won’t hit the city directly.”

From a safety point of view, it’s best to treat Friday and Saturday as the key risk window for Perth, keep an eye on updated warnings from the Bureau of Meteorology, and prepare for heavy rain, some power disruptions, and possible localised flooding rather than a direct eye-wall strike.
