Storm of the month

January (Tropical Depression 01W)

There was only one tropical cyclone studied in January. This storm was Tropical Depression 01W (003W 2017). This storm was hardly a depression and sure was depressing. On January 6 it was initially called Invest 96W (the 3rd invest of the season) and given a low chance of formation. By the 7th, it became a Tropical Depression, receiving the name Auring from PAGASA. Later, it made landfall in the Philippines as a very weak Tropical Depression/Remnant Low. The peak winds were 25kt and the lowest pressure was 1002mb during the first seven advisories. The JMA continued to classify and reclassify it as a depression for a number of days. By the 14th, JTWC put the risk at High, and the next day, the storm was upgraded to a Tropical Depression. 01W then interacted with Vietnam which caused the storm to fall apart on January 16, getting to 25kt and 1008mb. The total number of advisories was twelve.

February (Tropical Depression 98W/99W)

In February, the JTWC issued no tropical depressions. Despite this, the JMA upgraded Invest 98W to a tropical depression. After this, the invest was renamed Invest 99W.

March (Invest 90L)

In March, the Atlantic basin had a rare tropical disturbance. The disturbance was given a moderate chance of development but then they backed off. As soon as the models started to decrease the chances of development, the NHC upgraded the area to Invest 90L. No Special Outlooks were issued and the system didn't last long. Subtropical development did not occur and the system remained a normal low pressure system.
