Tropical Cyclone 18E (Terry)…is located about 845 miles south of the southern tip of Baja California
Tropical Cyclone 19E (Sandra)…is located about 790 miles southwest of the southern tip of Baja California

 

North Eastern Pacific

Tropical Cyclone 18E (Terry)

TERRY HOLDING STEADY IN STRENGTH

According to the NHC Advisory 19…The depression is moving toward the west near 14 mph (22 km/h) and a westward to west-northwestward motion is expected for the next few days.

Maximum sustained winds remain near 35 mph (55 km/h) with higher gusts.

Gradual weakening is forecast during the next few days, and Terry could become a remnant low or a trough during that time.

 

Tropical Cyclone 19E (Sandra)

SANDRA FORECAST TO DISSIPATE SOON

According to the NHC Advisory 7…The depression is moving toward the west near 15 mph (24 km/h), and this general motion is expected to continue for the next couple of days.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.

Weakening is forecast during the next day or two, and Sandra is expected to degenerate into a remnant low on Tuesday, and then dissipate by Wednesday.

 

North Central Pacific

Tropical cyclone formation is not expected during the next 5 days

North Western Pacific

No tropical cyclones or areas of disturbed weather under investigation by the JTWC

North Indian Ocean

There’s a tropical disturbance being referred to as Invest 91B…located approximately 616 NM east-southeast of Chennai, India

According to the JTWC…satellite imagery depicts broad mid to low level turning around an assessed low level circulation punctuated by disorganized convection.

Environmental analysis indicates a favorable environment for development with good westward and poleward outflow aloft, low (05-10 kt) wind shear and very warm sea surface temperatures.

Global models are good in agreement that invest 91B will track northwestward over the next 48 hours. GFS and NAVGEM are the more aggressive with development, whereas ECMWF and ICON are much more reserved.

Maximum sustained surface winds are estimated at 18-23 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours remains low.

South Indian Ocean

No tropical cyclones or areas of disturbed weather under investigation by the JTWC
