Quick answers

As of the Sat 26 Sep 12Z model run · updated Sat., Sept. 26, 9:58 p.m. UTC

Where is the low over Pakistan going?
The centre is about 400 kilometres north of Karachi, nearly stationary. The most likely path takes it about 270 kilometres north of Karachi by Monday night.
How sure is the forecast?
Medium confidence. 82 of 103 show the storm, and they broadly on its early path (agreement 61 out of 100).
Do the AI and physics models agree?
Largely, yes. By Monday night their middle tracks are almost on top of each other. Both take it to about 999 at its deepest.
Will the low over Pakistan become a bomb cyclone?
Unlikely. None of the 103 deepen it fast enough to count as a (a pressure fall of roughly 24 in 24 hours, adjusted for latitude).

Notes

  1. Forecast tracks from the 12Z model run: GEFS (31), AIFS ENS (51), GEPS (21). A single run is one high-resolution forecast; ensemble forecasts are the same model run many times with small changes.
  2. The cone encloses where the centre is expected to be about two times in three at each hour, from the spread of the forecasts, widened by 20 percent; not yet calibrated against past storms. It shows uncertainty in the track, not the size of the storm.
  3. Shading shows the share of forecasts that bring the centre within 160 kilometres of a spot at any time in the next 10 days. Rain, wind and surge can reach much farther.
  4. Times are in your time zone. Arrival windows run from the earliest to the latest closest approach across forecasts that bring the centre within about 300 miles (500 km).
