Tropical Depression Theta Discussion Number  22
NWS National Hurricane Center Miami FL       AL302020
900 AM GMT Sun Nov 15 2020

Theta is barely a tropical cyclone. The only remnants of deep
convection are a small area of warming cloud tops, located around
90 n mi to the southeast of Theta's exposed center. The cyclone has
produced little central convection all day, so it is assumed that at
least slight weakening has occurred and the intensity is set at
30 kt. This also agrees with a blend of the latest Dvorak Final-T
and CI numbers from TAFB. If Theta does not redevelop substantial
inner-core convection soon, it will likely become a remnant low
later today.

The cyclone has slowed down and is moving eastward with an initial
motion of 090/4 kt. A continued slow eastward track is expected
today, before a ridge centered over northwestern Africa begins to
steer the cyclone northward on Monday. Although Theta could continue
to produce intermittent bursts of convection, no significant
redevelopment is anticipated due to surrounding dry air and cool
underlying SSTs. The cyclone is forecast to become a remnant low
within 12 h and dissipate in 60 h. No major changes were made to the
NHC track or intensity forecasts, both of which are based on the
multi-model consensus aids.
