1. North Indian Ocean area (Malay Peninsula west to coast of Africa):
   a. Tropical cyclone summary: none.
   B. Tropical disturbance summary: none.
2. South Indian Ocean area (135e west to coast of Africa):
   a. Tropical cyclone summary:
      (1) at 191800z, tropical cyclone 19s (savannah) was located
near 18.6s 84.6e, approximately 987 nm southeast of Diego Garcia,
and had tracked west-southwestward at 06 knots over the past six
hours. Maximum sustained surface winds were estimated at 40 knots
gusting to 50 knots. See ref a (wtxs31 pgtw 192100) for further
details.
      (2) at 191800z, tropical cyclone 21s (veronica) was located
near 14.9s 119.7e, approximately 546 nm northeast of Learmonth,
Australia, and had tracked west-southwestward at 06 knots over the
past six hours. Maximum sustained surface winds were estimated at 40
knots gusting to 50 knots. See ref b (wtxs32 pgtw 192100) for
further details.
      (3) no other tropical cyclones.
   B. Tropical disturbance summary:
      (1) the area of convection previously located near 14.5s
120.0e, is now the subject of a tropical cyclone warning. See para.
2.A.(2) for further details.
      (2) the area of convection (invest 93s) previously located
near 12.3s 63.6e, is now located near 13.1s 63.1e, approximately 640
nm northeast of Saint-Denis, La Reunion. Animated infrared satellite
imagery and a 191731z 89ghz mhs microwave image depict a broad low
level circulation (llc) accompanied by disorganized, but flaring,
convection. A 191731z ascat pass shows 20-25 knot winds wrapping into
the circulation center. Upper level analysis depicts low (10-15kts)
vertical wind shear with favorable poleward and equatorward outflow.
Sea surface temperatures (28-30 celsius) in the surrounding waters
support future development. Global models indicate continued
near-term intensification, with the system reaching warning criteria
in 36-48 hours. Maximum sustained surface winds are estimated at 20
to 25 knots. Minimum sea level pressure is estimated to be near 1005
mb. Based on increasing organization and supportive environmental
conditions, the potential for the development of a significant
tropical cyclone within the next 24 hours is upgraded to medium.
      (3) no other suspect areas.
3. Justification for reissue: upgraded area in para 2.B.(1) to
warning status and upgraded area in para 2.B.(2) to medium.//
