As the cool anomalies continue to get pinched off over the central equatorial #Pacific, the SST anomalies & outgoing longwave radiation anomalies are resembling a #LaNina Modoki. #ElNino conditions should rapidly develop in the coming months.

The Pacific Meridional Mode went strongly positive in December & is expected to remain positive through at least summer. A strong +PMM in boreal spring tends to favor a +IOD in boreal autumn. The PMM & SPMM both being positive is a good signal for #ElNino later this year.

Conditions can become conducive for a tropical low to form near #Guam this weekend with a small chance to become a depression early next week. The slow-movement of any low will lead to rounds of heavy rain across the Northern Mariana Islands & Guam Saturday into early next week.
