Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis for the southern oregon coastal waters.. High pressure centered offshore and a thermal trough along the coast will continue moderate to strong north winds with steep to very steep seas through the weekend. Conditions will at least be hazardous to small craft, but warning level winds and seas will occur beyond 5 nautical miles from shore and south of gold beach through the period.

Discussion An upper ridge centered in the eastern pacific will
shift slightly east towards our area in the next 24-36 hours. This
will bring a continuation of hot and dry conditions over our area
through at least Friday. The latest visible image shows no cloud
cover over our area, but patchy to areas of smoke is evident at the
eclipse complex in western siskiyou county and chetco fire in curry
county. The upper winds carrying the smoke from northeast to
southwest. Of note it looks like most of the above mentioned fires
are becoming active as evidenced by the smoke plumes on the visible
The thermal trough remains just off the coast with offshore flow.
The chetco effect is in full force with brookings toping out at 94
degrees. It's has dropped down about 12 degrees in the past hour,
but were still expecting offshore flow to continue tonight with
gusty northeast winds and milder temperatures near and at the
Not much is going to change in the next couple of days with
continued offshore flow. The chetco effect will remain in place,
therefore expect mild temperatures at brookings tonight followed
by another warm day Friday. Skies should remain clear tonight,
including the coast, but we'll still have to deal with patchy to
areas of smoke.
A weak shortwave trough will ride over the ridge Saturday and could
bring slight cooling to most inland locations, but only by a few
degrees on average. The models show marginal instability at best,
but mid level moisture is lacking, so were not expecting any
thunderstorms. However, cumulus build ups are possible over the
mountains in northern california and east of the cascades.
The models show a weak upper trough developing in central california
Saturday night into Sunday and could tap into some monsoonal
moisture. The northward extent of the moisture should be confined to
northern california, specifically modoc county due in part to a
westerly flow setting up in the northern part of the forecast area.
There may be enough instability and moisture and weak trigger to
generate isolated thunderstorms. So kept in a slight chance in for
southeast modoc and lake county late Sunday afternoon evening.
The upper trough will close off and remain in central californaia
Monday and it remains to be seen how much moisture and instability
will move into our area. The GFS shows more instability, moisture
and slightly stronger trigger. The ECMWF is weaker with all of these
elements and has weak or almost nonexistent flow over us. Given the
model differences this far out, no changes will be made to the
coverage of slight chance of thunderstorms.
Tuesday afternoon and evening could turn out to be the most active
day in terms of thunderstorms. The GFS continues to be the most
bullish with plenty of moisture, instability and trigger. Right now,
most of the action should be in northern california and cascades
eastward. However steering winds could push some of these storms
into portions of the westside valleys, including the rogue and
illinois valley. Keep in mind this is still several days out and the
details on this could change from one day to the next. The bottom
line is confidence is becoming higher we could have an active day
Tuesday afternoon evening, but less confident on the exact location
of thunderstorms. Also could not rule nocturnal storms Tuesday night
east of the cascades.
Beyond Tuesday, we'll start to feel the influence of an upper low
moving southeast from the gulf of alaska towards vancouver island.
The models differ with position of the upper low. The ECMWF shows a
deeper trough which if correct would draw in moisture and
instability resulting in at least a slight chance for thunderstorms
east of the cascades. The GFS shows a southwest flow, keeping the
best chance for thunderstorms east of our area. Despite the
differences, both models suggest some cooling possible by next week|
at this time. It's a ways out and lot's could change, so stay tuned.
Aviation 17 18z TAF cycle...VFR will prevail across the area
today and tonight. Wildfire smoke will degrade visibility and could
create partial terrain obstruction. This smoke is affecting most
areas except for the coast and lake county. At the coast and
offshore, gusty north winds will be strongest south of CAPE blanco
this afternoon and evening. Stratus will return north of CAPE blanco
by 07z tonight. -spilde bs
Marine Updated 230 pm pdt Thursday 17 august 2017... High
pressure centered offshore and a thermal trough along the coast
will continue moderate to strong north winds and steep to very steep
seas through the weekend. Conditions will at least be hazardous to
small craft, but warning level winds seas will occur beyond 5 nm
from shore and south of gold beach through the period. Winds and
seas will be highest during the afternoons and evenings each day
through Sunday, easing a bit during the overnights and early
mornings. Model guidance shows peak boundary layer winds of ~50kt on
both Saturday and Sunday afternoons, then the pressure gradient
weakens with winds gradually easing early next week. Fb
Fire weather Updated 330 am Thursday 17 august 2017...
a thermal trough along the coast will maintain moderate northeast
offshore winds in the SW oregon coast range and portions of western
siskiyou county this morning. Humidity recoveries in these areas
have been poor to moderate, generally 35-45 percent at mid
slope ridge level, with wind speeds peaking at 10-15 mph. Occasional
gusts of 25-30 mph have been reported at a couple of the more
exposed raws like red mound and slater butte overnight.
It will remain very dry over much of the area today through the
weekend with daily minimum relative humidity in the 10-20% range
south of the umpqua divide and also east of the cascades. Nighttime
and early morning marine layer clouds will be confined to the
immediate coast north of CAPE blanco. Today will be very warm and
dry even on the southwest coast - a brookings effect is in full
force with the current temperature as of 3 am sitting at 81f.
Guidance indicates a high temperature there similar to yesterday, in
the low 90s with corresponding min rh in the upper 20s to near 30
percent. Expect some marine influence to raise min rh values a
bit there over the coming days, but it will remain lower than
High pressure aloft will flatten across the area today through
Friday allowing the atmosphere to become more unstable. High level
haines of 5 will be common west of the cascades today, then across
the entire area on Friday. Haines 6 is possible in portions
of fire zones 624 western 625 on Friday. Temperatures inland
will be back to 5-10 degrees above normal.
An offshore upper level disturbance will dig southeastward this
weekend and close off near the central southern california coast
early next week. It's still uncertain, but this may be able to
bring some moisture back to the north up the sierra crest and
eventually into portions of our forecast area. We are continuing to
indicate a slight chance of thunderstorms in modoc on Sunday
afternoon, then near the trinity alps medicine lake area into modoc
and perhaps goosenest area Monday afternoon. Models have come into
better alignment showing a better chance for lightning from the
cascades siskiyous eastward on Tuesday afternoon evening. -spilde
