Advisories for this week
- Moderate rain (about 39.3 mm) is coming — hold irrigation for 2–3 days and check soil moisture first.
- Monday 7: 98% 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 5 days — avoid open fields in the afternoon; when thunder sounds, shelter in a building, never under a tree.
- 5 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.
