Tropical Low 37U
High chance of a tropical cyclone south of the Solomon Islands from Sunday.

• A tropical low, 37U, is likely to form south of the Solomon Islands over the next few day.
• The environment is favourable for development and 37U has a Moderate chance of developing into a tropical cyclone from Saturday, increasing to a High chance from Sunday.
• 37U is expected to remain slow-moving over the weekend, before moving to the southwest next week.
• 37U is likely to remain well away from the Queensland coast over the next 7 days.

🚨 TROPICAL CYCLONE ADVICE: TROPICAL LOW (SOLOMON SEA)
Issued: 3pm 02/04/2026
The National Weather Service is monitoring a Tropical Low currently consolidating west of Guadalcanal. There is a Moderate to High chance of this system developing into a Tropical Cyclone by Sunday morning.
📍 Location: 110km West of Guadalcanal (9.6S 158.5E)
🌀 Intensity: 1003 hPa | Winds 15 knots (gusting higher)
⚠️ Status: Developing. Rapid intensification possible Sunday–Monday.
EXPECTED IMPACTS FOR PNG:
While the center remains near the Solomon Islands, the following hazards are expected for Bougainville, Milne Bay, and Southeast Coastal PNG:
