FIRST Choice Here is similar with sea level pressure gradients for easier comprehension. |
Summer-time system moves on shore---only SE 30 |
Below are 2 Satelite images from sea level
pressure gradients taken about 12 hours apart.
(August 10th and 11th 98). This is a summer
low pressure system, and though the winds are 30+
they are tame (few pressure gradients) compared to winter.
The low pressure system flattened out, but remains same with
winds as seen in yellow flag tails about same intensity and
direction. One can predict
winds will go NW 20+ in Dixon Entrance as the system passes (the
'back side of the low'). The timing is just not clear. Note the
JETSTREAM was similar to that shown below i.e., funneling over
Rupert.

On left
960 millibar low offshore. PR beginning cloud over. On right, 12 hours later, system edge over PR -- 1010 mbs and winds gusting SE 30 in Hecate. |

The AES
Weather Text site is good. Image on left is "astronomical"
for Rupert
just before dark Moon phase too. Gives previous
24 hourly readings. Compare these with Sandspit's.
Perfect. Chart on right from San Jose California newspaper. Paper good too (Silicon Valley). |

Here is Weatheroffice.com for Prince Rupert; and here are "trends" barometric readings over past day etc, which can give indication if system coming in or leaving.
A great NOAA site in US for severe weather warnings. Graphics heavy but gives radar, storms, rain, satellite imagery all from one page with hourly+ updates.

AES Western N. America
satellite imagery. (about 1/2 cropped off) Both taken same time -- On left is VISBLE and on right is INFRARED (pink area more severe weather) |

JET
STREAMS COMING in off the Pacific are harder to
interpret but, this is what it looked like just as a long stretch of clear weather was about to be replaced by systems coming off the Pacific Here is one Jet Streams for Northern hemisphere that allows longer predictions. |
Marine Weathers--- |
|
Weatheroffice.com has done a good job with the marine
weathers, better than land based.
The US site for same
weather buoy information has advantage of giving table
showing previous 20+ hourly observations for winds, sea state and
barometer. That information allows one to make ones own short
term weather predictions when combined with another site farther
West.

Seawater temperatures are often as critical as winds especially during summer. On left is NE Pacific and right is El Niņo site (links to La Niņa) |
