Chantal continues to produce an area of deep convection just
northeast of the mostly exposed low-level center. Recent
scatterometer data shows winds near 30 kt to the southeast east of
the center, and the initial intensity is again held at 30 kt. The
cyclone is moving toward warmer sea surface temperatures and into
an area of decreasing vertical wind shear. However, abundant dry
air and increasing upper-level convergence should cause the
system's convection to dissipate in 24 h or so. The new intensity
forecast is similar to the previous forecast in calling for the
cyclone to decay to a remna...

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical

Depression Chantal, located several hundred miles southeast of Cape

Race, Newfoundland.

A trough of low pressure located over the central and northwestern

Bahamas is producing disorganized showers and thunderstorms. Some

slow development is possible by this weekend or early next week

while the system moves northwestward toward the Florida peninsula at

5 to 10 mph and then turns northeastward off the southeastern coast

of the United States.

500 AM AST Thu Aug 22 2019

Chantal has been able to sustain an area of convection just to the
east of its low-level center since the last advisory, and final-T
numbers are actually back up to a unanimous T2.0/30 kt from TAFB and
SAB. The initial intensity is therefore held at 30 kt. The
depression is getting ready to move over a tongue of slightly warmer
waters, and vertical shear is forecast to decrease below 10 kt in a
day or two. However, there is abundant dry air around the system,
and upper-level convergence is expected to increase, both of which
should extinguish Chantal's organized deep convection in 24-36
hours. ...

Chantal's cloud pattern has become quite ragged during the past

intensity estimates from TAFB and SAB.

There are no changes to the philosophy of the intensity forecast.
