Satellite images indicate that a low pressure area has formed about
700 miles southwest of Manzanillo, Mexico, and is already showing
some signs of organization. Environmental conditions appear
conducive for further development, and a tropical depression is
likely to form over the weekend or early next week. The low is
forecast to move slowly westward over the next few days.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...70 percent.

[1900hurricane]

There's some pretty good apparent vorticity with this invest on visible imagery. Also worth noting how strong the westerly flow is on the south side of the monsoon trough.

Showers and thunderstorms associated with an area of low
pressure centered about 800 miles south-southwest of the southern
tip of the Baja California peninsula have changed little in
organization over the past several hours. Environmental conditions
are expected to support additional development and a tropical
depression is likely to form by early next week as the system moves
slowly westward.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...90 percent.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 13.0N 113.4W TO 14.9N 120.8W
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 25 TO 30 KNOTS. METSAT
IMAGERY AT 040100Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 13.2N 114.5W. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 10
KNOTS.
2. REMARKS: AN AREA OF CONVECTION (INVEST 94E) HAS PERSISTED NEAR
13.2N 114.5W, APPROXIMATELY 683 NM SOUTHWEST OF PUERTO VALLARTA.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS A CONSOLIDATING LOW
LEVEL CIRCULATION CENTER (LLCC) WITH CURVED, DEEPENING CONVECTION. A
032035Z AMSR2 GMI 89GHZ IMAGE SHOWS FORMATIVE BANDING BEGINNING TO
DEVELOP AROUND A WELL-DEVELOPED LLCC. THE UPPER LEVEL ENVIRONMENT IS
FAVORABLE FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (10-15 KT)
AND MODERATE EQUATORWARD OUTFLOW. SEA SURFACE TEMPERATURES (27-28C)
ARE FAVORABLE FOR DEVELOPMENT. NUMERICAL MODEL GUIDANCE IS IN GOOD
AGREEMENT ON FORECAST TRACK IN THE EARLY TAUS, TRACKING THE
CIRCULATION WEST-NORTHWEST; HOWEVER, THEY DISAGREE ON THE TIMING AND
DEGREE OF INTENSIFICATION. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
050230Z.//

Showers and thunderstorms associated with a broad area of low
pressure centered about 900 miles southwest of the southern tip of
the Baja California peninsula have changed little in organization
during the past few hours. However, environmental conditions appear
favorable for development, and a tropical depression is expected to
form by early next week while this system moves slowly westward.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.
