Rick storm forms October 15, 2009

Tropical storm Rick forms off Mexico Pacific coast

MEXICO CITY, Oct 15 (Reuters) - Tropical Storm Rick formed off Mexico's Pacific coast on Thursday and could become a hurricane within the next day, the U.S. National Hurricane Center said.

Rick was located 345 miles (555 km) south-southeast of the resort city of Acapulco with maximum sustained winds near 50 mph (85 kph).

"Continued strengthening is forecast during the next 48 hours," the Miami-based hurricane center said.

19 October 2009 - 09H03

AFP - Hurricane Rick weakened further early Monday and was downgraded to a Category 3 storm as it moved up Mexico's Pacific coast, US forecasters said.

"Maximum sustained winds have decreased to near 125 miles (205 kilometers) per hour with higher gusts," the National Hurricane Center said in an new advisory.

"Rick is a Category Three hurricane on the Saffir-Simpson scale," the center added.

At 0900 GMT Monday, Rick was around 380 miles (615 kilometers) south southwest of the resort town of Cabo San Lucas as it headed northwest at 10 miles (17 kilometers) per hour, parallel to Mexico's southern coast, the NHC said.

The US forecasters warned about "potentially dangerous surf conditions" caused by large ocean swells.

"Interests in western mainland Mexico should monitor the progress of this hurricane," the Miami-based center said.

Rick is on track to turn northward on Tuesday and is expected to gradually weaken over the next 24 to 48 hours, the NHC said.

But the center warned that even despite the weakening, "Rick is still expected to be a dangerous hurricane as it approaches the southern Baja Peninsula."

Column meaning:

TIME

Prior to 1962, times are UT1. Dates thereafter are UTC. Any 'b' symbol in
the 1st-column denotes a B.C. date. First-column blank (" ") denotes an A.D.
date. Calendar dates prior to 1582-Oct-15 are in the Julian calendar system.
Later calendar dates are in the Gregorian system.

The uniform Coordinate Time scale is used internally. Conversion between
CT and the selected non-uniform UT output scale has not been determined for
UTC times after the next July or January 1st. The last known leap-second
is used over any future interval.

NOTE: "n.a." in output means quantity "not available" at the print-time.

R.A._(ICRF/J2000.0)_DEC =
J2000.0 astrometric right ascension and declination of target center.
Corrected for light-time. Units: HMS (HH MM SS.ff) and DMS (DD MM SS.f)

APmag =
Asteroid's approximate apparent visual magnitude by following definition:
APmag = H + 5*log10(delta) + 5*log10(r) - 2.5*log10((1-G)*phi1 + G*phi2).
In principle, accurate to ~ +/- 0.1 magnitude. For solar phase angles > 90 deg,
the error could exceed 1 magnitude. No values are output for phase angles
greater than 120 degrees, since the extrapolation error could be large and
unknown. Units: NONE

delta deldot =
Range ("delta") and range-rate ("delta-dot") of target center with respect
to the observer at the instant light seen by the observer at print-time would
have left the target center (print-time minus down-leg light-time); the
distance traveled by a light ray emanating from the center of the target and
recorded by the observer at print-time. "deldot" is a projection of the
velocity vector along this ray, the light-time-corrected line-of-sight from the
coordinate center, and indicates relative motion. A positive "deldot" means the
target center is moving away from the observer (coordinate center). A negative
"deldot" means the target center is moving toward the observer.
Units: AU and KM/S

S-O-T /r =
Sun-Observer-Target angle; target's apparent solar elongation seen from
observer location at print-time. If negative, the target center is behind
the Sun. Angular units: DEGREES.

The '/r' column is a Sun-relative code, output for observing sites
with defined rotation models only.

/T indicates target trails Sun (evening sky)
/L indicates target leads Sun (morning sky)

NOTE: The S-O-T solar elongation angle is the total separation in any
direction. It does not indicate the angle of Sun leading or trailing.

S-T-O =
Sun-Target-Observer (~ PHASE ANGLE) angle: the vertex angle at target center
formed by a vector to the apparent center of the Sun and a vector intersecting
the observer at print-time. This measurable angle is within 20 arcseconds
(0.006 deg) of the reduced PHASE ANGLE at observer's location at print time.
The difference is due to down-leg stellar aberration affecting measured target
position but not apparent solar illumination direction. When computing phase,
Horizons uses the true phase angle, not S-T-O, but the resulting difference
in illuminated fraction is less than 0.001%.
Units: DEGREES
