Has Jaffna district had unusual rain in the last 3 days?
Not unusual
No. In the 3 days to Sat 26 Sept, 05:30, satellite rainfall was not in the wettest 1% of 3-day periods since 2000 for any DS division in Jaffna district. That is not a statement about safety; local downpours can be missed.

Each division's rain against its own record since June 2000: "Top 10%" means wetter than 90% of periods of the same length. "No data" means a total or baseline is missing, not that it was dry.
Limits
- This is a satellite estimate (NASA IMERG Early, about 11 km cells), not a warning and not a gauge reading.
- The satellite reads low over the hills, and an 11 km cell smooths out local downpours. "Not unusual" never means safe.
