Advisories for this week
- About 97.5 mm of rain is forecast over the next 7 days — no irrigation needed; clear drains so fields do not stay waterlogged, and raise vegetable beds.
- Monday 7: 97% chance of rain — do not leave cut paddy or jute drying in the open, and urea applied just before rain simply washes away.
- Thunderstorms likely on 6 days — avoid open fields in the afternoon; when thunder sounds, shelter in a building, never under a tree.
- 6 rainy days — fungal diseases (blast, sheath blight) spread fast on wet foliage; scout fields between showers.
Best days for field work
No dry, calm day in the next 7 days — do spraying and harvesting on the morning with the lowest rain chance, and check again tomorrow.

Sunamganj's main crops
Boro rice (haor), fish, duck farming, mustard — this week's rain and temperatures set the irrigation, disease and harvest timing for these.
Livestock, poultry and fish
- Improve airflow in poultry sheds and feed less at midday; keep cattle and goats in shade.
- Pond oxygen drops after heavy rain — if fish gasp at dawn, aerate (stir or pump water) and skip feeding that day; apply lime after heavy rain to correct pH; keep poultry housing dry.
