Ten (2020)

A tropical depression formed from a tropical wave that moved off the west coast of Africa on 28 July. The low developed along the wave axis and became Tropical Depression Ten at 1800 UTC 31 July about 200 nautical miles east of the easternmost Cabo Verde Islands. The system moved generally northwestward and then west‑northwestward around a larger upper‑level low, weakened as it encountered cool water and dry air, became a remnant low by 0000 UTC 2 August, and opened into a trough a few hours later. The depression never affected land.

There were no landfalls associated with this system.

The depression’s peak intensity was 30 kt (35 mph) with an estimated minimum central pressure of 1008 mb, reached around 1200 UTC 30 July (best‑track peak noted during its life). It remained a tropical depression throughout its short life and did not reach tropical storm strength.

No storm surge or rainfall impacts were reported because the system remained well offshore and did not affect inhabited areas. There are no recorded surge heights or rainfall totals for cities or counties associated with this system.

There were no casualties or damage reported.

Noteworthy items: the cyclone’s genesis was not well anticipated—NHC first placed the disturbance in the Tropical Weather Outlook about 36 hours before formation and only gave it a medium (40–60%) chance of developing 24 hours before genesis. Forecast track and intensity errors for the few verifying forecasts were smaller than recent 5‑year means, but the system’s short lifespan limited forecast verification.
