Wash people off beaches and rocks, and capsize small boats RipĬurrents can pull swimmers and surfers out to sea. There is an increased risk of ocean drowning. High tide over beach areas including bike paths and walkways,Įspecially Wednesday and Thursday. * IMPACTS.Pooling of sea water is possible around the time of * WHEN.From 6 PM PDT this evening through Thursday evening. * WHERE.South facing shores of Los Angeles and Ventura Counties. * WHAT.Dangerous rip currents and breaking waves due to elevated BEACH HAZARDS STATEMENT IN EFFECT FROM 6 PM PDT THIS EVENING Although this is the peak risk of G1/minor storm for the period as a whole, it only offers a slight chance of Minor Geomagnetic Storm G1, with Quiet conditions predominant until then.Įnergetic Particles / Solar Radiati on: No solar radiation storms are expected - although after the recent Moderate-class flare in the southeast, a slight risk of a minor solar radiation storm remains for day 1 (17 May).Effective: T01:00:00+00:00 Expires: T06:00:00+00:00 Certainty: Event: Beach Hazards Statement Type: Severity: Urgency: Areas: Solar Wind / Geomagnetic Activity: No CMEs now feature in the four-day forecast.īeyond the possible current marginal influence of the high latitude coronal hole, the only coronal hole fast wind due in the four days is minor and mooted for Friday 19 May. Solar Activity: Solar activity will be initially Low, with a Chance of becoming Moderate after midweek UTC, with the expected arrival of a CME-producing sunspot region over the southeast limb, with no significant regions departing off the disc. The net effect of the above solar wind measures was for Quiet to Unsettled geomagnetic activity.Įnergetic Particles / Solar Radiation: No solar radiation storms were observed. one that does not have a particularly direct route to affect Earth - instead largely passing over the track of the Earth's orbit. Solar Wind / Geomagnetic Activity: The solar wind speed has been a slightly elevated levels throughout, although the mechanism for this is not certain, but maybe connected to a high latitude coronal hole fast wind i.e. No Earth-directed CMEs have been observed in the past 24 hours. The partial halo CME may be associated with a recently departed active sunspot group, which is now on the far-side of the Sun. However, coincidently a partial halo CME emerged off the north and west limb following the event, which has been analysed and is considered to be far-sided, with no Earth-directed component. Surprisingly, only a very faint Coronal Mass Ejection (CME) has emerged off the SE limb following the recent significant Moderate-class flare, which is yet to be analysed. However, this region has not shown any significant flare activity in the last 24 hours, and appears to be relatively stable. The sunspot group located in the northeast (just west of the meridian line) is the largest and most magnetically complex. There are currently six numbered sunspot regions on the visible disc, with two unnumbered regions. Otherwise, X-ray activity has been confined to minor C-class flares. This region is expected to rotate onto the visible disc in the next 24 hours. Solar Activity: Solar activity has been High over the last 24 hours, with the largest event a significant Moderate-class flare, which was observed at 16/1643 UTC, originating from a sunspot region which is yet to emerge onto the Earth-facing disc. Space Weather Forecast Headline: Slight chance of Moderate X-ray flares and R1/R2 radio blackouts, perhaps rising after midweek. Slight chance (10%) of G1 minor storm days 3 and 4 due to arrival of fast wind from a coronal hole.Īnalysis of Space Weather Activity over past 24 hours
